Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525082, here are decompositions:

409 + 31524673 = 31525082
439 + 31524643 = 31525082
541 + 31524541 = 31525082
613 + 31524469 = 31525082
739 + 31524343 = 31525082
751 + 31524331 = 31525082
811 + 31524271 = 31525082
859 + 31524223 = 31525082

Showing the first eight; more decompositions exist.
