Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525044, here are decompositions:

7 + 31525037 = 31525044
13 + 31525031 = 31525044
17 + 31525027 = 31525044
37 + 31525007 = 31525044
53 + 31524991 = 31525044
107 + 31524937 = 31525044
151 + 31524893 = 31525044
181 + 31524863 = 31525044

Showing the first eight; more decompositions exist.
