Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507376, here are decompositions:

13 + 31507363 = 31507376
79 + 31507297 = 31507376
367 + 31507009 = 31507376
547 + 31506829 = 31507376
577 + 31506799 = 31507376
853 + 31506523 = 31507376
1009 + 31506367 = 31507376
1093 + 31506283 = 31507376

Showing the first eight; more decompositions exist.
