Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525466, here are decompositions:

19 + 31525447 = 31525466
199 + 31525267 = 31525466
223 + 31525243 = 31525466
283 + 31525183 = 31525466
439 + 31525027 = 31525466
499 + 31524967 = 31525466
673 + 31524793 = 31525466
823 + 31524643 = 31525466

Showing the first eight; more decompositions exist.
