Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507838, here are decompositions:

11 + 507827 = 507838
17 + 507821 = 507838
29 + 507809 = 507838
41 + 507797 = 507838
59 + 507779 = 507838
197 + 507641 = 507838
239 + 507599 = 507838
281 + 507557 = 507838

Showing the first eight; more decompositions exist.
