Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505920, here are decompositions:

13 + 505907 = 505920
43 + 505877 = 505920
53 + 505867 = 505920
97 + 505823 = 505920
101 + 505819 = 505920
109 + 505811 = 505920
139 + 505781 = 505920
157 + 505763 = 505920

Showing the first eight; more decompositions exist.
