Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525058, here are decompositions:

31 + 31525027 = 31525058
67 + 31524991 = 31525058
337 + 31524721 = 31525058
541 + 31524517 = 31525058
727 + 31524331 = 31525058
757 + 31524301 = 31525058
787 + 31524271 = 31525058
967 + 31524091 = 31525058

Showing the first eight; more decompositions exist.
