Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981226, here are decompositions:

5 + 981221 = 981226
17 + 981209 = 981226
53 + 981173 = 981226
89 + 981137 = 981226
149 + 981077 = 981226
227 + 980999 = 981226
263 + 980963 = 981226
269 + 980957 = 981226

Showing the first eight; more decompositions exist.
