Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525252, here are decompositions:

23 + 31525229 = 31525252
41 + 31525211 = 31525252
89 + 31525163 = 31525252
131 + 31525121 = 31525252
149 + 31525103 = 31525252
263 + 31524989 = 31525252
359 + 31524893 = 31525252
389 + 31524863 = 31525252

Showing the first eight; more decompositions exist.
