Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605088, here are decompositions:

17 + 31605071 = 31605088
41 + 31605047 = 31605088
59 + 31605029 = 31605088
71 + 31605017 = 31605088
101 + 31604987 = 31605088
239 + 31604849 = 31605088
401 + 31604687 = 31605088
461 + 31604627 = 31605088

Showing the first eight; more decompositions exist.
