Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556726, here are decompositions:

73 + 31556653 = 31556726
79 + 31556647 = 31556726
337 + 31556389 = 31556726
373 + 31556353 = 31556726
433 + 31556293 = 31556726
577 + 31556149 = 31556726
613 + 31556113 = 31556726
727 + 31555999 = 31556726

Showing the first eight; more decompositions exist.
