Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611506, here are decompositions:

19 + 31611487 = 31611506
67 + 31611439 = 31611506
103 + 31611403 = 31611506
127 + 31611379 = 31611506
139 + 31611367 = 31611506
379 + 31611127 = 31611506
439 + 31611067 = 31611506
457 + 31611049 = 31611506

Showing the first eight; more decompositions exist.
