Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557634, here are decompositions:

23 + 31557611 = 31557634
71 + 31557563 = 31557634
131 + 31557503 = 31557634
191 + 31557443 = 31557634
197 + 31557437 = 31557634
233 + 31557401 = 31557634
257 + 31557377 = 31557634
431 + 31557203 = 31557634

Showing the first eight; more decompositions exist.
