Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507482, here are decompositions:

23 + 31507459 = 31507482
79 + 31507403 = 31507482
131 + 31507351 = 31507482
163 + 31507319 = 31507482
199 + 31507283 = 31507482
211 + 31507271 = 31507482
239 + 31507243 = 31507482
271 + 31507211 = 31507482

Showing the first eight; more decompositions exist.
