Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513276, here are decompositions:

17 + 31513259 = 31513276
83 + 31513193 = 31513276
89 + 31513187 = 31513276
227 + 31513049 = 31513276
239 + 31513037 = 31513276
269 + 31513007 = 31513276
317 + 31512959 = 31513276
383 + 31512893 = 31513276

Showing the first eight; more decompositions exist.
