Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525178, here are decompositions:

151 + 31525027 = 31525178
211 + 31524967 = 31525178
241 + 31524937 = 31525178
457 + 31524721 = 31525178
571 + 31524607 = 31525178
661 + 31524517 = 31525178
709 + 31524469 = 31525178
877 + 31524301 = 31525178

Showing the first eight; more decompositions exist.
