Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537684, here are decompositions:

53 + 31537631 = 31537684
137 + 31537547 = 31537684
251 + 31537433 = 31537684
293 + 31537391 = 31537684
461 + 31537223 = 31537684
557 + 31537127 = 31537684
587 + 31537097 = 31537684
641 + 31537043 = 31537684

Showing the first eight; more decompositions exist.
