Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513958, here are decompositions:

41 + 513917 = 513958
59 + 513899 = 513958
191 + 513767 = 513958
197 + 513761 = 513958
227 + 513731 = 513958
239 + 513719 = 513958
317 + 513641 = 513958
449 + 513509 = 513958

Showing the first eight; more decompositions exist.
