Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551322, here are decompositions:

11 + 551311 = 551322
41 + 551281 = 551322
53 + 551269 = 551322
89 + 551233 = 551322
103 + 551219 = 551322
179 + 551143 = 551322
193 + 551129 = 551322
223 + 551099 = 551322

Showing the first eight; more decompositions exist.
