Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517334, here are decompositions:

61 + 31517273 = 31517334
67 + 31517267 = 31517334
103 + 31517231 = 31517334
127 + 31517207 = 31517334
137 + 31517197 = 31517334
271 + 31517063 = 31517334
307 + 31517027 = 31517334
313 + 31517021 = 31517334

Showing the first eight; more decompositions exist.
