Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626540, here are decompositions:

11 + 8626529 = 8626540
23 + 8626517 = 8626540
47 + 8626493 = 8626540
53 + 8626487 = 8626540
71 + 8626469 = 8626540
149 + 8626391 = 8626540
191 + 8626349 = 8626540
239 + 8626301 = 8626540

Showing the first eight; more decompositions exist.
