Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616608, here are decompositions:

5 + 31616603 = 31616608
29 + 31616579 = 31616608
47 + 31616561 = 31616608
197 + 31616411 = 31616608
227 + 31616381 = 31616608
239 + 31616369 = 31616608
269 + 31616339 = 31616608
281 + 31616327 = 31616608

Showing the first eight; more decompositions exist.
