Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622540, here are decompositions:

11 + 8622529 = 8622540
19 + 8622521 = 8622540
29 + 8622511 = 8622540
41 + 8622499 = 8622540
53 + 8622487 = 8622540
67 + 8622473 = 8622540
71 + 8622469 = 8622540
79 + 8622461 = 8622540

Showing the first eight; more decompositions exist.
