Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622838, here are decompositions:

71 + 8622767 = 8622838
131 + 8622707 = 8622838
227 + 8622611 = 8622838
317 + 8622521 = 8622838
347 + 8622491 = 8622838
479 + 8622359 = 8622838
647 + 8622191 = 8622838
701 + 8622137 = 8622838

Showing the first eight; more decompositions exist.
