Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616776, here are decompositions:

3 + 31616773 = 31616776
29 + 31616747 = 31616776
47 + 31616729 = 31616776
83 + 31616693 = 31616776
89 + 31616687 = 31616776
173 + 31616603 = 31616776
197 + 31616579 = 31616776
353 + 31616423 = 31616776

Showing the first eight; more decompositions exist.
