Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616734, here are decompositions:

5 + 31616729 = 31616734
41 + 31616693 = 31616734
47 + 31616687 = 31616734
131 + 31616603 = 31616734
173 + 31616561 = 31616734
311 + 31616423 = 31616734
353 + 31616381 = 31616734
503 + 31616231 = 31616734

Showing the first eight; more decompositions exist.
