Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507422, here are decompositions:

19 + 31507403 = 31507422
59 + 31507363 = 31507422
61 + 31507361 = 31507422
71 + 31507351 = 31507422
101 + 31507321 = 31507422
103 + 31507319 = 31507422
139 + 31507283 = 31507422
151 + 31507271 = 31507422

Showing the first eight; more decompositions exist.
