Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616460, here are decompositions:

37 + 31616423 = 31616460
41 + 31616419 = 31616460
59 + 31616401 = 31616460
67 + 31616393 = 31616460
79 + 31616381 = 31616460
97 + 31616363 = 31616460
101 + 31616359 = 31616460
163 + 31616297 = 31616460

Showing the first eight; more decompositions exist.
