Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979646, here are decompositions:

79 + 979567 = 979646
97 + 979549 = 979646
103 + 979543 = 979646
127 + 979519 = 979646
223 + 979423 = 979646
277 + 979369 = 979646
313 + 979333 = 979646
373 + 979273 = 979646

Showing the first eight; more decompositions exist.
