Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981268, here are decompositions:

5 + 981263 = 981268
47 + 981221 = 981268
59 + 981209 = 981268
131 + 981137 = 981268
191 + 981077 = 981268
251 + 981017 = 981268
257 + 981011 = 981268
269 + 980999 = 981268

Showing the first eight; more decompositions exist.
