Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517074, here are decompositions:

11 + 31517063 = 31517074
47 + 31517027 = 31517074
53 + 31517021 = 31517074
101 + 31516973 = 31517074
233 + 31516841 = 31517074
263 + 31516811 = 31517074
293 + 31516781 = 31517074
317 + 31516757 = 31517074

Showing the first eight; more decompositions exist.
