Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507676, here are decompositions:

43 + 31507633 = 31507676
103 + 31507573 = 31507676
313 + 31507363 = 31507676
379 + 31507297 = 31507676
433 + 31507243 = 31507676
727 + 31506949 = 31507676
769 + 31506907 = 31507676
853 + 31506823 = 31507676

Showing the first eight; more decompositions exist.
