Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525256, here are decompositions:

13 + 31525243 = 31525256
43 + 31525213 = 31525256
73 + 31525183 = 31525256
79 + 31525177 = 31525256
229 + 31525027 = 31525256
463 + 31524793 = 31525256
613 + 31524643 = 31525256
733 + 31524523 = 31525256

Showing the first eight; more decompositions exist.
