Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979580, here are decompositions:

13 + 979567 = 979580
31 + 979549 = 979580
37 + 979543 = 979580
61 + 979519 = 979580
109 + 979471 = 979580
157 + 979423 = 979580
211 + 979369 = 979580
307 + 979273 = 979580

Showing the first eight; more decompositions exist.
