Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981304, here are decompositions:

3 + 981301 = 981304
17 + 981287 = 981304
41 + 981263 = 981304
83 + 981221 = 981304
131 + 981173 = 981304
167 + 981137 = 981304
227 + 981077 = 981304
281 + 981023 = 981304

Showing the first eight; more decompositions exist.
