Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605634, here are decompositions:

41 + 31605593 = 31605634
83 + 31605551 = 31605634
191 + 31605443 = 31605634
227 + 31605407 = 31605634
233 + 31605401 = 31605634
257 + 31605377 = 31605634
491 + 31605143 = 31605634
563 + 31605071 = 31605634

Showing the first eight; more decompositions exist.
