Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525576, here are decompositions:

23 + 31525553 = 31525576
179 + 31525397 = 31525576
197 + 31525379 = 31525576
233 + 31525343 = 31525576
293 + 31525283 = 31525576
347 + 31525229 = 31525576
449 + 31525127 = 31525576
569 + 31525007 = 31525576

Showing the first eight; more decompositions exist.
