Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525422, here are decompositions:

43 + 31525379 = 31525422
79 + 31525343 = 31525422
139 + 31525283 = 31525422
179 + 31525243 = 31525422
193 + 31525229 = 31525422
211 + 31525211 = 31525422
239 + 31525183 = 31525422
431 + 31524991 = 31525422

Showing the first eight; more decompositions exist.
