Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616344, here are decompositions:

5 + 31616339 = 31616344
17 + 31616327 = 31616344
47 + 31616297 = 31616344
83 + 31616261 = 31616344
113 + 31616231 = 31616344
311 + 31616033 = 31616344
587 + 31615757 = 31616344
761 + 31615583 = 31616344

Showing the first eight; more decompositions exist.
