Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 579780, here are decompositions:

7 + 579773 = 579780
17 + 579763 = 579780
23 + 579757 = 579780
43 + 579737 = 579780
59 + 579721 = 579780
67 + 579713 = 579780
73 + 579707 = 579780
79 + 579701 = 579780

Showing the first eight; more decompositions exist.
