Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517978, here are decompositions:

11 + 517967 = 517978
29 + 517949 = 517978
47 + 517931 = 517978
59 + 517919 = 517978
101 + 517877 = 517978
239 + 517739 = 517978
257 + 517721 = 517978
359 + 517619 = 517978

Showing the first eight; more decompositions exist.
