Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659942, here are decompositions:

3 + 8659939 = 8659942
29 + 8659913 = 8659942
131 + 8659811 = 8659942
149 + 8659793 = 8659942
173 + 8659769 = 8659942
251 + 8659691 = 8659942
311 + 8659631 = 8659942
353 + 8659589 = 8659942

Showing the first eight; more decompositions exist.
