Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505470, here are decompositions:

11 + 505459 = 505470
23 + 505447 = 505470
41 + 505429 = 505470
59 + 505411 = 505470
61 + 505409 = 505470
71 + 505399 = 505470
101 + 505369 = 505470
103 + 505367 = 505470

Showing the first eight; more decompositions exist.
