Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981276, here are decompositions:

5 + 981271 = 981276
13 + 981263 = 981276
67 + 981209 = 981276
89 + 981187 = 981276
103 + 981173 = 981276
137 + 981139 = 981276
139 + 981137 = 981276
199 + 981077 = 981276

Showing the first eight; more decompositions exist.
