Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574684, here are decompositions:

3 + 31574681 = 31574684
7 + 31574677 = 31574684
13 + 31574671 = 31574684
241 + 31574443 = 31574684
577 + 31574107 = 31574684
613 + 31574071 = 31574684
643 + 31574041 = 31574684
727 + 31573957 = 31574684

Showing the first eight; more decompositions exist.
