Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525316, here are decompositions:

37 + 31525279 = 31525316
73 + 31525243 = 31525316
103 + 31525213 = 31525316
139 + 31525177 = 31525316
349 + 31524967 = 31525316
379 + 31524937 = 31525316
523 + 31524793 = 31525316
643 + 31524673 = 31525316

Showing the first eight; more decompositions exist.
