Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605036, here are decompositions:

7 + 31605029 = 31605036
17 + 31605019 = 31605036
19 + 31605017 = 31605036
103 + 31604933 = 31605036
173 + 31604863 = 31605036
233 + 31604803 = 31605036
269 + 31604767 = 31605036
277 + 31604759 = 31605036

Showing the first eight; more decompositions exist.
