Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616084, here are decompositions:

37 + 31616047 = 31616084
43 + 31616041 = 31616084
61 + 31616023 = 31616084
67 + 31616017 = 31616084
163 + 31615921 = 31616084
193 + 31615891 = 31616084
277 + 31615807 = 31616084
373 + 31615711 = 31616084

Showing the first eight; more decompositions exist.
