Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525196, here are decompositions:

13 + 31525183 = 31525196
19 + 31525177 = 31525196
229 + 31524967 = 31525196
433 + 31524763 = 31525196
523 + 31524673 = 31525196
673 + 31524523 = 31525196
727 + 31524469 = 31525196
853 + 31524343 = 31525196

Showing the first eight; more decompositions exist.
