Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525214, here are decompositions:

3 + 31525211 = 31525214
13 + 31525201 = 31525214
31 + 31525183 = 31525214
37 + 31525177 = 31525214
223 + 31524991 = 31525214
277 + 31524937 = 31525214
421 + 31524793 = 31525214
541 + 31524673 = 31525214

Showing the first eight; more decompositions exist.
