Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613594, here are decompositions:

13 + 31613581 = 31613594
43 + 31613551 = 31613594
157 + 31613437 = 31613594
193 + 31613401 = 31613594
211 + 31613383 = 31613594
367 + 31613227 = 31613594
457 + 31613137 = 31613594
487 + 31613107 = 31613594

Showing the first eight; more decompositions exist.
