Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559804, here are decompositions:

127 + 31559677 = 31559804
151 + 31559653 = 31559804
163 + 31559641 = 31559804
181 + 31559623 = 31559804
337 + 31559467 = 31559804
421 + 31559383 = 31559804
433 + 31559371 = 31559804
487 + 31559317 = 31559804

Showing the first eight; more decompositions exist.
