Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507294, here are decompositions:

11 + 31507283 = 31507294
23 + 31507271 = 31507294
83 + 31507211 = 31507294
113 + 31507181 = 31507294
257 + 31507037 = 31507294
317 + 31506977 = 31507294
383 + 31506911 = 31507294
503 + 31506791 = 31507294

Showing the first eight; more decompositions exist.
