Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550816, here are decompositions:

3 + 550813 = 550816
5 + 550811 = 550816
53 + 550763 = 550816
59 + 550757 = 550816
83 + 550733 = 550816
113 + 550703 = 550816
137 + 550679 = 550816
179 + 550637 = 550816

Showing the first eight; more decompositions exist.
