Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556904, here are decompositions:

47 + 31556857 = 31556904
101 + 31556803 = 31556904
157 + 31556747 = 31556904
163 + 31556741 = 31556904
167 + 31556737 = 31556904
251 + 31556653 = 31556904
257 + 31556647 = 31556904
347 + 31556557 = 31556904

Showing the first eight; more decompositions exist.
