Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506828, here are decompositions:

19 + 506809 = 506828
31 + 506797 = 506828
37 + 506791 = 506828
97 + 506731 = 506828
139 + 506689 = 506828
181 + 506647 = 506828
199 + 506629 = 506828
229 + 506599 = 506828

Showing the first eight; more decompositions exist.
