Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588414, here are decompositions:

47 + 31588367 = 31588414
83 + 31588331 = 31588414
101 + 31588313 = 31588414
107 + 31588307 = 31588414
167 + 31588247 = 31588414
257 + 31588157 = 31588414
311 + 31588103 = 31588414
353 + 31588061 = 31588414

Showing the first eight; more decompositions exist.
