Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525052, here are decompositions:

61 + 31524991 = 31525052
331 + 31524721 = 31525052
379 + 31524673 = 31525052
409 + 31524643 = 31525052
709 + 31524343 = 31525052
751 + 31524301 = 31525052
829 + 31524223 = 31525052
859 + 31524193 = 31525052

Showing the first eight; more decompositions exist.
