Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622438, here are decompositions:

17 + 8622421 = 8622438
47 + 8622391 = 8622438
59 + 8622379 = 8622438
79 + 8622359 = 8622438
101 + 8622337 = 8622438
107 + 8622331 = 8622438
131 + 8622307 = 8622438
137 + 8622301 = 8622438

Showing the first eight; more decompositions exist.
