Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507366, here are decompositions:

3 + 31507363 = 31507366
5 + 31507361 = 31507366
47 + 31507319 = 31507366
83 + 31507283 = 31507366
167 + 31507199 = 31507366
227 + 31507139 = 31507366
257 + 31507109 = 31507366
389 + 31506977 = 31507366

Showing the first eight; more decompositions exist.
