C++ creating huge vector

For a process I'm trying to run I need to have a std::vector of std::tuple<long unsigned int, long unsigned int>. The test I'm doing right now should create a vector of 47,614,527,250 (around 47 billion) tuples but actually crashes right there on creation with the error terminate called after throwing an instance of 'std::bad_alloc'. My goal is to use this script with a vector roughly twice that size. The code is this:

arc_vector = std::vector<std::tuple<long unsigned int, long unsigned int>>(arcs);

where arcs is a long unsigned int with the cited value.

Can I, and in that case how do I, increase the memory size? This script is running on a 40-core machine with something like 200GB of memory so I know memory itself is not an issue.
