Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616704, here are decompositions:

11 + 31616693 = 31616704
17 + 31616687 = 31616704
101 + 31616603 = 31616704
281 + 31616423 = 31616704
293 + 31616411 = 31616704
311 + 31616393 = 31616704
443 + 31616261 = 31616704
521 + 31616183 = 31616704

Showing the first eight; more decompositions exist.
