Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525332, here are decompositions:

43 + 31525289 = 31525332
53 + 31525279 = 31525332
71 + 31525261 = 31525332
89 + 31525243 = 31525332
103 + 31525229 = 31525332
131 + 31525201 = 31525332
149 + 31525183 = 31525332
211 + 31525121 = 31525332

Showing the first eight; more decompositions exist.
