Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605832, here are decompositions:

23 + 31605809 = 31605832
29 + 31605803 = 31605832
53 + 31605779 = 31605832
59 + 31605773 = 31605832
113 + 31605719 = 31605832
131 + 31605701 = 31605832
239 + 31605593 = 31605832
281 + 31605551 = 31605832

Showing the first eight; more decompositions exist.
