Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525086, here are decompositions:

59 + 31525027 = 31525086
79 + 31525007 = 31525086
97 + 31524989 = 31525086
149 + 31524937 = 31525086
193 + 31524893 = 31525086
223 + 31524863 = 31525086
277 + 31524809 = 31525086
293 + 31524793 = 31525086

Showing the first eight; more decompositions exist.
