Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979820, here are decompositions:

13 + 979807 = 979820
73 + 979747 = 979820
103 + 979717 = 979820
271 + 979549 = 979820
277 + 979543 = 979820
349 + 979471 = 979820
397 + 979423 = 979820
487 + 979333 = 979820

Showing the first eight; more decompositions exist.
