Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525294, here are decompositions:

5 + 31525289 = 31525294
11 + 31525283 = 31525294
83 + 31525211 = 31525294
131 + 31525163 = 31525294
167 + 31525127 = 31525294
173 + 31525121 = 31525294
191 + 31525103 = 31525294
257 + 31525037 = 31525294

Showing the first eight; more decompositions exist.
