Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622516, here are decompositions:

5 + 8622511 = 8622516
17 + 8622499 = 8622516
29 + 8622487 = 8622516
43 + 8622473 = 8622516
47 + 8622469 = 8622516
53 + 8622463 = 8622516
103 + 8622413 = 8622516
137 + 8622379 = 8622516

Showing the first eight; more decompositions exist.
