Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659020, here are decompositions:

11 + 8659009 = 8659020
23 + 8658997 = 8659020
31 + 8658989 = 8659020
37 + 8658983 = 8659020
43 + 8658977 = 8659020
59 + 8658961 = 8659020
61 + 8658959 = 8659020
79 + 8658941 = 8659020

Showing the first eight; more decompositions exist.
