Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525594, here are decompositions:

5 + 31525589 = 31525594
41 + 31525553 = 31525594
173 + 31525421 = 31525594
197 + 31525397 = 31525594
227 + 31525367 = 31525594
251 + 31525343 = 31525594
263 + 31525331 = 31525594
311 + 31525283 = 31525594

Showing the first eight; more decompositions exist.
