Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525360, here are decompositions:

17 + 31525343 = 31525360
29 + 31525331 = 31525360
71 + 31525289 = 31525360
131 + 31525229 = 31525360
149 + 31525211 = 31525360
197 + 31525163 = 31525360
233 + 31525127 = 31525360
239 + 31525121 = 31525360

Showing the first eight; more decompositions exist.
