Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508818, here are decompositions:

7 + 508811 = 508818
19 + 508799 = 508818
29 + 508789 = 508818
47 + 508771 = 508818
109 + 508709 = 508818
157 + 508661 = 508818
181 + 508637 = 508818
197 + 508621 = 508818

Showing the first eight; more decompositions exist.
