Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551006, here are decompositions:

3 + 551003 = 551006
13 + 550993 = 551006
37 + 550969 = 551006
67 + 550939 = 551006
97 + 550909 = 551006
103 + 550903 = 551006
163 + 550843 = 551006
193 + 550813 = 551006

Showing the first eight; more decompositions exist.
