Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550866, here are decompositions:

5 + 550861 = 550866
7 + 550859 = 550866
23 + 550843 = 550866
53 + 550813 = 550866
103 + 550763 = 550866
109 + 550757 = 550866
149 + 550717 = 550866
163 + 550703 = 550866

Showing the first eight; more decompositions exist.
