Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622528, here are decompositions:

7 + 8622521 = 8622528
17 + 8622511 = 8622528
29 + 8622499 = 8622528
37 + 8622491 = 8622528
41 + 8622487 = 8622528
59 + 8622469 = 8622528
67 + 8622461 = 8622528
107 + 8622421 = 8622528

Showing the first eight; more decompositions exist.
