Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525306, here are decompositions:

17 + 31525289 = 31525306
23 + 31525283 = 31525306
179 + 31525127 = 31525306
269 + 31525037 = 31525306
317 + 31524989 = 31525306
443 + 31524863 = 31525306
467 + 31524839 = 31525306
509 + 31524797 = 31525306

Showing the first eight; more decompositions exist.
