Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556996, here are decompositions:

73 + 31556923 = 31556996
127 + 31556869 = 31556996
139 + 31556857 = 31556996
193 + 31556803 = 31556996
349 + 31556647 = 31556996
439 + 31556557 = 31556996
607 + 31556389 = 31556996
643 + 31556353 = 31556996

Showing the first eight; more decompositions exist.
