Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622866, here are decompositions:

13 + 8622853 = 8622866
19 + 8622847 = 8622866
73 + 8622793 = 8622866
103 + 8622763 = 8622866
337 + 8622529 = 8622866
367 + 8622499 = 8622866
379 + 8622487 = 8622866
397 + 8622469 = 8622866

Showing the first eight; more decompositions exist.
