Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508806, here are decompositions:

7 + 508799 = 508806
17 + 508789 = 508806
79 + 508727 = 508806
97 + 508709 = 508806
113 + 508693 = 508806
163 + 508643 = 508806
223 + 508583 = 508806
227 + 508579 = 508806

Showing the first eight; more decompositions exist.
