Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507350, here are decompositions:

29 + 31507321 = 31507350
31 + 31507319 = 31507350
53 + 31507297 = 31507350
67 + 31507283 = 31507350
79 + 31507271 = 31507350
107 + 31507243 = 31507350
139 + 31507211 = 31507350
151 + 31507199 = 31507350

Showing the first eight; more decompositions exist.
