Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556684, here are decompositions:

31 + 31556653 = 31556684
37 + 31556647 = 31556684
127 + 31556557 = 31556684
223 + 31556461 = 31556684
277 + 31556407 = 31556684
331 + 31556353 = 31556684
541 + 31556143 = 31556684
571 + 31556113 = 31556684

Showing the first eight; more decompositions exist.
