Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525022, here are decompositions:

31 + 31524991 = 31525022
229 + 31524793 = 31525022
349 + 31524673 = 31525022
379 + 31524643 = 31525022
499 + 31524523 = 31525022
523 + 31524499 = 31525022
619 + 31524403 = 31525022
691 + 31524331 = 31525022

Showing the first eight; more decompositions exist.
