Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505814, here are decompositions:

3 + 505811 = 505814
37 + 505777 = 505814
103 + 505711 = 505814
151 + 505663 = 505814
157 + 505657 = 505814
181 + 505633 = 505814
241 + 505573 = 505814
277 + 505537 = 505814

Showing the first eight; more decompositions exist.
