Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517858, here are decompositions:

41 + 517817 = 517858
137 + 517721 = 517858
239 + 517619 = 517858
269 + 517589 = 517858
281 + 517577 = 517858
311 + 517547 = 517858
347 + 517511 = 517858
359 + 517499 = 517858

Showing the first eight; more decompositions exist.
