Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525514, here are decompositions:

37 + 31525477 = 31525514
67 + 31525447 = 31525514
271 + 31525243 = 31525514
313 + 31525201 = 31525514
331 + 31525183 = 31525514
337 + 31525177 = 31525514
487 + 31525027 = 31525514
523 + 31524991 = 31525514

Showing the first eight; more decompositions exist.
