Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543634, here are decompositions:

103 + 31543531 = 31543634
181 + 31543453 = 31543634
643 + 31542991 = 31543634
691 + 31542943 = 31543634
757 + 31542877 = 31543634
823 + 31542811 = 31543634
907 + 31542727 = 31543634
937 + 31542697 = 31543634

Showing the first eight; more decompositions exist.
