Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512426, here are decompositions:

17 + 31512409 = 31512426
67 + 31512359 = 31512426
79 + 31512347 = 31512426
83 + 31512343 = 31512426
137 + 31512289 = 31512426
167 + 31512259 = 31512426
173 + 31512253 = 31512426
227 + 31512199 = 31512426

Showing the first eight; more decompositions exist.
