Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515908, here are decompositions:

47 + 515861 = 515908
131 + 515777 = 515908
137 + 515771 = 515908
167 + 515741 = 515908
227 + 515681 = 515908
257 + 515651 = 515908
269 + 515639 = 515908
311 + 515597 = 515908

Showing the first eight; more decompositions exist.
