Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556908, here are decompositions:

137 + 31556771 = 31556908
167 + 31556741 = 31556908
269 + 31556639 = 31556908
419 + 31556489 = 31556908
431 + 31556477 = 31556908
491 + 31556417 = 31556908
599 + 31556309 = 31556908
659 + 31556249 = 31556908

Showing the first eight; more decompositions exist.
