Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492126, here are decompositions:

47 + 31492079 = 31492126
53 + 31492073 = 31492126
59 + 31492067 = 31492126
137 + 31491989 = 31492126
167 + 31491959 = 31492126
233 + 31491893 = 31492126
389 + 31491737 = 31492126
467 + 31491659 = 31492126

Showing the first eight; more decompositions exist.
