Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505548, here are decompositions:

11 + 505537 = 505548
37 + 505511 = 505548
47 + 505501 = 505548
67 + 505481 = 505548
79 + 505469 = 505548
89 + 505459 = 505548
101 + 505447 = 505548
137 + 505411 = 505548

Showing the first eight; more decompositions exist.
