Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616998, here are decompositions:

11 + 31616987 = 31616998
47 + 31616951 = 31616998
107 + 31616891 = 31616998
251 + 31616747 = 31616998
269 + 31616729 = 31616998
311 + 31616687 = 31616998
419 + 31616579 = 31616998
587 + 31616411 = 31616998

Showing the first eight; more decompositions exist.
