Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551206, here are decompositions:

107 + 551099 = 551206
113 + 551093 = 551206
137 + 551069 = 551206
167 + 551039 = 551206
179 + 551027 = 551206
233 + 550973 = 551206
269 + 550937 = 551206
347 + 550859 = 551206

Showing the first eight; more decompositions exist.
