Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620806, here are decompositions:

59 + 8620747 = 8620806
67 + 8620739 = 8620806
79 + 8620727 = 8620806
83 + 8620723 = 8620806
167 + 8620639 = 8620806
239 + 8620567 = 8620806
263 + 8620543 = 8620806
277 + 8620529 = 8620806

Showing the first eight; more decompositions exist.
