Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508686, here are decompositions:

43 + 508643 = 508686
67 + 508619 = 508686
103 + 508583 = 508686
107 + 508579 = 508686
109 + 508577 = 508686
127 + 508559 = 508686
137 + 508549 = 508686
173 + 508513 = 508686

Showing the first eight; more decompositions exist.
