Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999256, here are decompositions:

17 + 999239 = 999256
23 + 999233 = 999256
107 + 999149 = 999256
173 + 999083 = 999256
227 + 999029 = 999256
233 + 999023 = 999256
347 + 998909 = 999256
359 + 998897 = 999256

Showing the first eight; more decompositions exist.
