Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513946, here are decompositions:

3 + 513943 = 513946
23 + 513923 = 513946
29 + 513917 = 513946
47 + 513899 = 513946
107 + 513839 = 513946
179 + 513767 = 513946
197 + 513749 = 513946
227 + 513719 = 513946

Showing the first eight; more decompositions exist.
