Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525206, here are decompositions:

5 + 31525201 = 31525206
23 + 31525183 = 31525206
29 + 31525177 = 31525206
43 + 31525163 = 31525206
79 + 31525127 = 31525206
103 + 31525103 = 31525206
179 + 31525027 = 31525206
199 + 31525007 = 31525206

Showing the first eight; more decompositions exist.
