Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645806, here are decompositions:

3 + 8645803 = 8645806
17 + 8645789 = 8645806
47 + 8645759 = 8645806
137 + 8645669 = 8645806
149 + 8645657 = 8645806
173 + 8645633 = 8645806
227 + 8645579 = 8645806
263 + 8645543 = 8645806

Showing the first eight; more decompositions exist.
