Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507496, here are decompositions:

37 + 31507459 = 31507496
199 + 31507297 = 31507496
337 + 31507159 = 31507496
379 + 31507117 = 31507496
409 + 31507087 = 31507496
487 + 31507009 = 31507496
523 + 31506973 = 31507496
547 + 31506949 = 31507496

Showing the first eight; more decompositions exist.
