Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505476, here are decompositions:

7 + 505469 = 505476
17 + 505459 = 505476
29 + 505447 = 505476
47 + 505429 = 505476
67 + 505409 = 505476
107 + 505369 = 505476
109 + 505367 = 505476
137 + 505339 = 505476

Showing the first eight; more decompositions exist.
