Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525218, here are decompositions:

5 + 31525213 = 31525218
7 + 31525211 = 31525218
17 + 31525201 = 31525218
41 + 31525177 = 31525218
97 + 31525121 = 31525218
181 + 31525037 = 31525218
191 + 31525027 = 31525218
211 + 31525007 = 31525218

Showing the first eight; more decompositions exist.
