Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525180, here are decompositions:

3 + 31525177 = 31525180
17 + 31525163 = 31525180
53 + 31525127 = 31525180
59 + 31525121 = 31525180
149 + 31525031 = 31525180
173 + 31525007 = 31525180
191 + 31524989 = 31525180
317 + 31524863 = 31525180

Showing the first eight; more decompositions exist.
