Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556744, here are decompositions:

3 + 31556741 = 31556744
7 + 31556737 = 31556744
97 + 31556647 = 31556744
277 + 31556467 = 31556744
283 + 31556461 = 31556744
337 + 31556407 = 31556744
421 + 31556323 = 31556744
601 + 31556143 = 31556744

Showing the first eight; more decompositions exist.
