Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616914, here are decompositions:

11 + 31616903 = 31616914
23 + 31616891 = 31616914
167 + 31616747 = 31616914
227 + 31616687 = 31616914
311 + 31616603 = 31616914
353 + 31616561 = 31616914
491 + 31616423 = 31616914
503 + 31616411 = 31616914

Showing the first eight; more decompositions exist.
