Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517094, here are decompositions:

31 + 31517063 = 31517094
67 + 31517027 = 31517094
73 + 31517021 = 31517094
83 + 31517011 = 31517094
101 + 31516993 = 31517094
113 + 31516981 = 31517094
283 + 31516811 = 31517094
307 + 31516787 = 31517094

Showing the first eight; more decompositions exist.
