Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508666, here are decompositions:

5 + 508661 = 508666
23 + 508643 = 508666
29 + 508637 = 508666
47 + 508619 = 508666
83 + 508583 = 508666
89 + 508577 = 508666
107 + 508559 = 508666
149 + 508517 = 508666

Showing the first eight; more decompositions exist.
