Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981256, here are decompositions:

47 + 981209 = 981256
83 + 981173 = 981256
179 + 981077 = 981256
233 + 981023 = 981256
239 + 981017 = 981256
257 + 980999 = 981256
293 + 980963 = 981256
347 + 980909 = 981256

Showing the first eight; more decompositions exist.
