Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517908, here are decompositions:

7 + 517901 = 517908
31 + 517877 = 517908
47 + 517861 = 517908
179 + 517729 = 517908
191 + 517717 = 517908
197 + 517711 = 517908
269 + 517639 = 517908
271 + 517637 = 517908

Showing the first eight; more decompositions exist.
