Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525414, here are decompositions:

17 + 31525397 = 31525414
47 + 31525367 = 31525414
71 + 31525343 = 31525414
83 + 31525331 = 31525414
131 + 31525283 = 31525414
251 + 31525163 = 31525414
293 + 31525121 = 31525414
311 + 31525103 = 31525414

Showing the first eight; more decompositions exist.
