Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505836, here are decompositions:

13 + 505823 = 505836
17 + 505819 = 505836
59 + 505777 = 505836
73 + 505763 = 505836
109 + 505727 = 505836
127 + 505709 = 505836
167 + 505669 = 505836
173 + 505663 = 505836

Showing the first eight; more decompositions exist.
