Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613452, here are decompositions:

11 + 31613441 = 31613452
41 + 31613411 = 31613452
53 + 31613399 = 31613452
281 + 31613171 = 31613452
461 + 31612991 = 31613452
491 + 31612961 = 31613452
599 + 31612853 = 31613452
719 + 31612733 = 31613452

Showing the first eight; more decompositions exist.
