Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518608, here are decompositions:

11 + 518597 = 518608
29 + 518579 = 518608
137 + 518471 = 518608
179 + 518429 = 518608
191 + 518417 = 518608
197 + 518411 = 518608
281 + 518327 = 518608
317 + 518291 = 518608

Showing the first eight; more decompositions exist.
