Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505804, here are decompositions:

23 + 505781 = 505804
41 + 505763 = 505804
113 + 505691 = 505804
191 + 505613 = 505804
197 + 505607 = 505804
281 + 505523 = 505804
293 + 505511 = 505804
311 + 505493 = 505804

Showing the first eight; more decompositions exist.
