Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505636, here are decompositions:

3 + 505633 = 505636
17 + 505619 = 505636
23 + 505613 = 505636
29 + 505607 = 505636
113 + 505523 = 505636
167 + 505469 = 505636
227 + 505409 = 505636
269 + 505367 = 505636

Showing the first eight; more decompositions exist.
