Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525562, here are decompositions:

73 + 31525489 = 31525562
283 + 31525279 = 31525562
349 + 31525213 = 31525562
379 + 31525183 = 31525562
571 + 31524991 = 31525562
769 + 31524793 = 31525562
919 + 31524643 = 31525562
1021 + 31524541 = 31525562

Showing the first eight; more decompositions exist.
