Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525166, here are decompositions:

3 + 31525163 = 31525166
139 + 31525027 = 31525166
199 + 31524967 = 31525166
229 + 31524937 = 31525166
373 + 31524793 = 31525166
523 + 31524643 = 31525166
643 + 31524523 = 31525166
823 + 31524343 = 31525166

Showing the first eight; more decompositions exist.
