Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622420, here are decompositions:

7 + 8622413 = 8622420
29 + 8622391 = 8622420
41 + 8622379 = 8622420
47 + 8622373 = 8622420
61 + 8622359 = 8622420
67 + 8622353 = 8622420
83 + 8622337 = 8622420
89 + 8622331 = 8622420

Showing the first eight; more decompositions exist.
