Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490934, here are decompositions:

17 + 31490917 = 31490934
113 + 31490821 = 31490934
127 + 31490807 = 31490934
193 + 31490741 = 31490934
227 + 31490707 = 31490934
257 + 31490677 = 31490934
283 + 31490651 = 31490934
311 + 31490623 = 31490934

Showing the first eight; more decompositions exist.
