Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991246, here are decompositions:

17 + 991229 = 991246
23 + 991223 = 991246
29 + 991217 = 991246
59 + 991187 = 991246
167 + 991079 = 991246
173 + 991073 = 991246
257 + 990989 = 991246
293 + 990953 = 991246

Showing the first eight; more decompositions exist.
