Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659900, here are decompositions:

89 + 8659811 = 8659900
107 + 8659793 = 8659900
131 + 8659769 = 8659900
233 + 8659667 = 8659900
257 + 8659643 = 8659900
269 + 8659631 = 8659900
311 + 8659589 = 8659900
443 + 8659457 = 8659900

Showing the first eight; more decompositions exist.
