Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616836, here are decompositions:

89 + 31616747 = 31616836
107 + 31616729 = 31616836
149 + 31616687 = 31616836
233 + 31616603 = 31616836
257 + 31616579 = 31616836
443 + 31616393 = 31616836
467 + 31616369 = 31616836
509 + 31616327 = 31616836

Showing the first eight; more decompositions exist.
