Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551170, here are decompositions:

41 + 551129 = 551170
71 + 551099 = 551170
101 + 551069 = 551170
107 + 551063 = 551170
131 + 551039 = 551170
167 + 551003 = 551170
173 + 550997 = 551170
197 + 550973 = 551170

Showing the first eight; more decompositions exist.
