Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622806, here are decompositions:

13 + 8622793 = 8622806
43 + 8622763 = 8622806
229 + 8622577 = 8622806
277 + 8622529 = 8622806
307 + 8622499 = 8622806
337 + 8622469 = 8622806
433 + 8622373 = 8622806
463 + 8622343 = 8622806

Showing the first eight; more decompositions exist.
