Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550566, here are decompositions:

13 + 550553 = 550566
47 + 550519 = 550566
53 + 550513 = 550566
97 + 550469 = 550566
109 + 550457 = 550566
127 + 550439 = 550566
139 + 550427 = 550566
197 + 550369 = 550566

Showing the first eight; more decompositions exist.
