Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525502, here are decompositions:

3 + 31525499 = 31525502
13 + 31525489 = 31525502
223 + 31525279 = 31525502
241 + 31525261 = 31525502
709 + 31524793 = 31525502
739 + 31524763 = 31525502
829 + 31524673 = 31525502
859 + 31524643 = 31525502

Showing the first eight; more decompositions exist.
