Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476516, here are decompositions:

7 + 31476509 = 31476516
17 + 31476499 = 31476516
59 + 31476457 = 31476516
67 + 31476449 = 31476516
79 + 31476437 = 31476516
83 + 31476433 = 31476516
103 + 31476413 = 31476516
163 + 31476353 = 31476516

Showing the first eight; more decompositions exist.
