Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517304, here are decompositions:

31 + 31517273 = 31517304
37 + 31517267 = 31517304
61 + 31517243 = 31517304
73 + 31517231 = 31517304
97 + 31517207 = 31517304
107 + 31517197 = 31517304
241 + 31517063 = 31517304
277 + 31517027 = 31517304

Showing the first eight; more decompositions exist.
