Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525170, here are decompositions:

7 + 31525163 = 31525170
43 + 31525127 = 31525170
67 + 31525103 = 31525170
139 + 31525031 = 31525170
163 + 31525007 = 31525170
179 + 31524991 = 31525170
181 + 31524989 = 31525170
233 + 31524937 = 31525170

Showing the first eight; more decompositions exist.
