Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616902, here are decompositions:

11 + 31616891 = 31616902
173 + 31616729 = 31616902
479 + 31616423 = 31616902
491 + 31616411 = 31616902
509 + 31616393 = 31616902
521 + 31616381 = 31616902
563 + 31616339 = 31616902
641 + 31616261 = 31616902

Showing the first eight; more decompositions exist.
