Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622390, here are decompositions:

11 + 8622379 = 8622390
17 + 8622373 = 8622390
31 + 8622359 = 8622390
37 + 8622353 = 8622390
47 + 8622343 = 8622390
53 + 8622337 = 8622390
59 + 8622331 = 8622390
67 + 8622323 = 8622390

Showing the first eight; more decompositions exist.
