Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608010, here are decompositions:

41 + 31607969 = 31608010
89 + 31607921 = 31608010
101 + 31607909 = 31608010
107 + 31607903 = 31608010
113 + 31607897 = 31608010
179 + 31607831 = 31608010
227 + 31607783 = 31608010
263 + 31607747 = 31608010

Showing the first eight; more decompositions exist.
