Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659242, here are decompositions:

19 + 8659223 = 8659242
23 + 8659219 = 8659242
61 + 8659181 = 8659242
89 + 8659153 = 8659242
181 + 8659061 = 8659242
191 + 8659051 = 8659242
199 + 8659043 = 8659242
223 + 8659019 = 8659242

Showing the first eight; more decompositions exist.
