Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512094, here are decompositions:

11 + 31512083 = 31512094
23 + 31512071 = 31512094
71 + 31512023 = 31512094
83 + 31512011 = 31512094
101 + 31511993 = 31512094
113 + 31511981 = 31512094
167 + 31511927 = 31512094
227 + 31511867 = 31512094

Showing the first eight; more decompositions exist.
