Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656806, here are decompositions:

5 + 8656801 = 8656806
19 + 8656787 = 8656806
47 + 8656759 = 8656806
73 + 8656733 = 8656806
79 + 8656727 = 8656806
139 + 8656667 = 8656806
229 + 8656577 = 8656806
233 + 8656573 = 8656806

Showing the first eight; more decompositions exist.
