Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659906, here are decompositions:

113 + 8659793 = 8659906
137 + 8659769 = 8659906
239 + 8659667 = 8659906
263 + 8659643 = 8659906
317 + 8659589 = 8659906
347 + 8659559 = 8659906
443 + 8659463 = 8659906
449 + 8659457 = 8659906

Showing the first eight; more decompositions exist.
