Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525668, here are decompositions:

11 + 31525657 = 31525668
17 + 31525651 = 31525668
19 + 31525649 = 31525668
59 + 31525609 = 31525668
61 + 31525607 = 31525668
67 + 31525601 = 31525668
79 + 31525589 = 31525668
101 + 31525567 = 31525668

Showing the first eight; more decompositions exist.
