Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525456, here are decompositions:

59 + 31525397 = 31525456
89 + 31525367 = 31525456
113 + 31525343 = 31525456
167 + 31525289 = 31525456
173 + 31525283 = 31525456
227 + 31525229 = 31525456
293 + 31525163 = 31525456
353 + 31525103 = 31525456

Showing the first eight; more decompositions exist.
