Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622558, here are decompositions:

29 + 8622529 = 8622558
37 + 8622521 = 8622558
47 + 8622511 = 8622558
59 + 8622499 = 8622558
67 + 8622491 = 8622558
71 + 8622487 = 8622558
89 + 8622469 = 8622558
97 + 8622461 = 8622558

Showing the first eight; more decompositions exist.
