Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525396, here are decompositions:

17 + 31525379 = 31525396
29 + 31525367 = 31525396
53 + 31525343 = 31525396
107 + 31525289 = 31525396
113 + 31525283 = 31525396
167 + 31525229 = 31525396
233 + 31525163 = 31525396
269 + 31525127 = 31525396

Showing the first eight; more decompositions exist.
