Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517216, here are decompositions:

5 + 517211 = 517216
47 + 517169 = 517216
137 + 517079 = 517216
149 + 517067 = 517216
173 + 517043 = 517216
239 + 516977 = 517216
257 + 516959 = 517216
269 + 516947 = 517216

Showing the first eight; more decompositions exist.
