Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519858, here are decompositions:

41 + 519817 = 519858
61 + 519797 = 519858
71 + 519787 = 519858
89 + 519769 = 519858
167 + 519691 = 519858
191 + 519667 = 519858
211 + 519647 = 519858
239 + 519619 = 519858

Showing the first eight; more decompositions exist.
