Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525354, here are decompositions:

11 + 31525343 = 31525354
23 + 31525331 = 31525354
71 + 31525283 = 31525354
191 + 31525163 = 31525354
227 + 31525127 = 31525354
233 + 31525121 = 31525354
251 + 31525103 = 31525354
317 + 31525037 = 31525354

Showing the first eight; more decompositions exist.
