Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513966, here are decompositions:

23 + 513943 = 513966
29 + 513937 = 513966
43 + 513923 = 513966
67 + 513899 = 513966
127 + 513839 = 513966
137 + 513829 = 513966
197 + 513769 = 513966
199 + 513767 = 513966

Showing the first eight; more decompositions exist.
