Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616982, here are decompositions:

31 + 31616951 = 31616982
53 + 31616929 = 31616982
79 + 31616903 = 31616982
233 + 31616749 = 31616982
311 + 31616671 = 31616982
359 + 31616623 = 31616982
379 + 31616603 = 31616982
421 + 31616561 = 31616982

Showing the first eight; more decompositions exist.
