Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616932, here are decompositions:

3 + 31616929 = 31616932
29 + 31616903 = 31616932
41 + 31616891 = 31616932
239 + 31616693 = 31616932
353 + 31616579 = 31616932
509 + 31616423 = 31616932
521 + 31616411 = 31616932
563 + 31616369 = 31616932

Showing the first eight; more decompositions exist.
