Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622430, here are decompositions:

17 + 8622413 = 8622430
71 + 8622359 = 8622430
107 + 8622323 = 8622430
137 + 8622293 = 8622430
239 + 8622191 = 8622430
293 + 8622137 = 8622430
317 + 8622113 = 8622430
359 + 8622071 = 8622430

Showing the first eight; more decompositions exist.
