Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626966, here are decompositions:

233 + 8626733 = 8626966
269 + 8626697 = 8626966
353 + 8626613 = 8626966
389 + 8626577 = 8626966
449 + 8626517 = 8626966
479 + 8626487 = 8626966
617 + 8626349 = 8626966
683 + 8626283 = 8626966

Showing the first eight; more decompositions exist.
