Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517276, here are decompositions:

3 + 31517273 = 31517276
79 + 31517197 = 31517276
127 + 31517149 = 31517276
283 + 31516993 = 31517276
397 + 31516879 = 31517276
457 + 31516819 = 31517276
487 + 31516789 = 31517276
499 + 31516777 = 31517276

Showing the first eight; more decompositions exist.
