Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670256, here are decompositions:

17 + 8670239 = 8670256
59 + 8670197 = 8670256
149 + 8670107 = 8670256
167 + 8670089 = 8670256
227 + 8670029 = 8670256
263 + 8669993 = 8670256
293 + 8669963 = 8670256
317 + 8669939 = 8670256

Showing the first eight; more decompositions exist.
