Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981214, here are decompositions:

5 + 981209 = 981214
41 + 981173 = 981214
137 + 981077 = 981214
191 + 981023 = 981214
197 + 981017 = 981214
251 + 980963 = 981214
257 + 980957 = 981214
293 + 980921 = 981214

Showing the first eight; more decompositions exist.
