Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551146, here are decompositions:

3 + 551143 = 551146
17 + 551129 = 551146
47 + 551099 = 551146
53 + 551093 = 551146
83 + 551063 = 551146
107 + 551039 = 551146
149 + 550997 = 551146
173 + 550973 = 551146

Showing the first eight; more decompositions exist.
