Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505822, here are decompositions:

3 + 505819 = 505822
11 + 505811 = 505822
41 + 505781 = 505822
59 + 505763 = 505822
113 + 505709 = 505822
131 + 505691 = 505822
179 + 505643 = 505822
263 + 505559 = 505822

Showing the first eight; more decompositions exist.
