Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600820, here are decompositions:

13 + 8600807 = 8600820
31 + 8600789 = 8600820
37 + 8600783 = 8600820
43 + 8600777 = 8600820
73 + 8600747 = 8600820
79 + 8600741 = 8600820
101 + 8600719 = 8600820
103 + 8600717 = 8600820

Showing the first eight; more decompositions exist.
