Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525190, here are decompositions:

7 + 31525183 = 31525190
13 + 31525177 = 31525190
163 + 31525027 = 31525190
199 + 31524991 = 31525190
223 + 31524967 = 31525190
397 + 31524793 = 31525190
547 + 31524643 = 31525190
673 + 31524517 = 31525190

Showing the first eight; more decompositions exist.
