Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542118, here are decompositions:

5 + 31542113 = 31542118
107 + 31542011 = 31542118
137 + 31541981 = 31542118
227 + 31541891 = 31542118
467 + 31541651 = 31542118
521 + 31541597 = 31542118
701 + 31541417 = 31542118
719 + 31541399 = 31542118

Showing the first eight; more decompositions exist.
