Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505526, here are decompositions:

3 + 505523 = 505526
13 + 505513 = 505526
67 + 505459 = 505526
79 + 505447 = 505526
97 + 505429 = 505526
127 + 505399 = 505526
157 + 505369 = 505526
199 + 505327 = 505526

Showing the first eight; more decompositions exist.
