Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518794, here are decompositions:

47 + 518747 = 518794
53 + 518741 = 518794
137 + 518657 = 518794
173 + 518621 = 518794
197 + 518597 = 518794
251 + 518543 = 518794
347 + 518447 = 518794
383 + 518411 = 518794

Showing the first eight; more decompositions exist.
