Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525490, here are decompositions:

13 + 31525477 = 31525490
43 + 31525447 = 31525490
211 + 31525279 = 31525490
223 + 31525267 = 31525490
229 + 31525261 = 31525490
277 + 31525213 = 31525490
307 + 31525183 = 31525490
313 + 31525177 = 31525490

Showing the first eight; more decompositions exist.
