Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556732, here are decompositions:

79 + 31556653 = 31556732
271 + 31556461 = 31556732
379 + 31556353 = 31556732
409 + 31556323 = 31556732
439 + 31556293 = 31556732
619 + 31556113 = 31556732
733 + 31555999 = 31556732
751 + 31555981 = 31556732

Showing the first eight; more decompositions exist.
