Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525674, here are decompositions:

17 + 31525657 = 31525674
23 + 31525651 = 31525674
67 + 31525607 = 31525674
71 + 31525603 = 31525674
73 + 31525601 = 31525674
107 + 31525567 = 31525674
137 + 31525537 = 31525674
197 + 31525477 = 31525674

Showing the first eight; more decompositions exist.
