Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525188, here are decompositions:

5 + 31525183 = 31525188
11 + 31525177 = 31525188
61 + 31525127 = 31525188
67 + 31525121 = 31525188
151 + 31525037 = 31525188
157 + 31525031 = 31525188
181 + 31525007 = 31525188
197 + 31524991 = 31525188

Showing the first eight; more decompositions exist.
