Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556626, here are decompositions:

89 + 31556537 = 31556626
137 + 31556489 = 31556626
149 + 31556477 = 31556626
317 + 31556309 = 31556626
347 + 31556279 = 31556626
383 + 31556243 = 31556626
593 + 31556033 = 31556626
659 + 31555967 = 31556626

Showing the first eight; more decompositions exist.
