Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505650, here are decompositions:

7 + 505643 = 505650
11 + 505639 = 505650
17 + 505633 = 505650
31 + 505619 = 505650
37 + 505613 = 505650
43 + 505607 = 505650
113 + 505537 = 505650
127 + 505523 = 505650

Showing the first eight; more decompositions exist.
