Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517314, here are decompositions:

41 + 31517273 = 31517314
47 + 31517267 = 31517314
71 + 31517243 = 31517314
83 + 31517231 = 31517314
107 + 31517207 = 31517314
251 + 31517063 = 31517314
293 + 31517021 = 31517314
503 + 31516811 = 31517314

Showing the first eight; more decompositions exist.
