Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505626, here are decompositions:

7 + 505619 = 505626
13 + 505613 = 505626
19 + 505607 = 505626
53 + 505573 = 505626
67 + 505559 = 505626
89 + 505537 = 505626
103 + 505523 = 505626
113 + 505513 = 505626

Showing the first eight; more decompositions exist.
