Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525300, here are decompositions:

11 + 31525289 = 31525300
17 + 31525283 = 31525300
71 + 31525229 = 31525300
89 + 31525211 = 31525300
137 + 31525163 = 31525300
173 + 31525127 = 31525300
179 + 31525121 = 31525300
197 + 31525103 = 31525300

Showing the first eight; more decompositions exist.
