Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505506, here are decompositions:

5 + 505501 = 505506
13 + 505493 = 505506
37 + 505469 = 505506
47 + 505459 = 505506
59 + 505447 = 505506
97 + 505409 = 505506
107 + 505399 = 505506
137 + 505369 = 505506

Showing the first eight; more decompositions exist.
