Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505524, here are decompositions:

11 + 505513 = 505524
13 + 505511 = 505524
23 + 505501 = 505524
31 + 505493 = 505524
43 + 505481 = 505524
113 + 505411 = 505524
157 + 505367 = 505524
167 + 505357 = 505524

Showing the first eight; more decompositions exist.
