Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505568, here are decompositions:

31 + 505537 = 505568
67 + 505501 = 505568
109 + 505459 = 505568
139 + 505429 = 505568
157 + 505411 = 505568
199 + 505369 = 505568
211 + 505357 = 505568
229 + 505339 = 505568

Showing the first eight; more decompositions exist.
