Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507808, here are decompositions:

5 + 507803 = 507808
11 + 507797 = 507808
29 + 507779 = 507808
89 + 507719 = 507808
167 + 507641 = 507808
251 + 507557 = 507808
311 + 507497 = 507808
317 + 507491 = 507808

Showing the first eight; more decompositions exist.
