Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517214, here are decompositions:

7 + 31517207 = 31517214
17 + 31517197 = 31517214
151 + 31517063 = 31517214
193 + 31517021 = 31517214
233 + 31516981 = 31517214
241 + 31516973 = 31517214
263 + 31516951 = 31517214
373 + 31516841 = 31517214

Showing the first eight; more decompositions exist.
