Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551066, here are decompositions:

3 + 551063 = 551066
7 + 551059 = 551066
73 + 550993 = 551066
97 + 550969 = 551066
127 + 550939 = 551066
157 + 550909 = 551066
163 + 550903 = 551066
223 + 550843 = 551066

Showing the first eight; more decompositions exist.
