Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517720, here are decompositions:

3 + 517717 = 517720
83 + 517637 = 517720
101 + 517619 = 517720
107 + 517613 = 517720
131 + 517589 = 517720
149 + 517571 = 517720
167 + 517553 = 517720
173 + 517547 = 517720

Showing the first eight; more decompositions exist.
