Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516976, here are decompositions:

3 + 31516973 = 31516976
97 + 31516879 = 31516976
157 + 31516819 = 31516976
199 + 31516777 = 31516976
223 + 31516753 = 31516976
277 + 31516699 = 31516976
307 + 31516669 = 31516976
349 + 31516627 = 31516976

Showing the first eight; more decompositions exist.
