Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550728, here are decompositions:

7 + 550721 = 550728
11 + 550717 = 550728
37 + 550691 = 550728
67 + 550661 = 550728
71 + 550657 = 550728
97 + 550631 = 550728
107 + 550621 = 550728
151 + 550577 = 550728

Showing the first eight; more decompositions exist.
