Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607010, here are decompositions:

13 + 31606997 = 31607010
31 + 31606979 = 31607010
37 + 31606973 = 31607010
47 + 31606963 = 31607010
53 + 31606957 = 31607010
59 + 31606951 = 31607010
67 + 31606943 = 31607010
79 + 31606931 = 31607010

Showing the first eight; more decompositions exist.
