Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513938, here are decompositions:

67 + 513871 = 513938
97 + 513841 = 513938
109 + 513829 = 513938
157 + 513781 = 513938
199 + 513739 = 513938
211 + 513727 = 513938
241 + 513697 = 513938
307 + 513631 = 513938

Showing the first eight; more decompositions exist.
