Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622480, here are decompositions:

7 + 8622473 = 8622480
11 + 8622469 = 8622480
17 + 8622463 = 8622480
19 + 8622461 = 8622480
59 + 8622421 = 8622480
67 + 8622413 = 8622480
89 + 8622391 = 8622480
101 + 8622379 = 8622480

Showing the first eight; more decompositions exist.
