Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626630, here are decompositions:

17 + 8626613 = 8626630
53 + 8626577 = 8626630
101 + 8626529 = 8626630
113 + 8626517 = 8626630
137 + 8626493 = 8626630
239 + 8626391 = 8626630
281 + 8626349 = 8626630
347 + 8626283 = 8626630

Showing the first eight; more decompositions exist.
