Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550878, here are decompositions:

17 + 550861 = 550878
19 + 550859 = 550878
37 + 550841 = 550878
47 + 550831 = 550878
67 + 550811 = 550878
89 + 550789 = 550878
157 + 550721 = 550878
199 + 550679 = 550878

Showing the first eight; more decompositions exist.
