Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551164, here are decompositions:

71 + 551093 = 551164
101 + 551063 = 551164
137 + 551027 = 551164
167 + 550997 = 551164
191 + 550973 = 551164
227 + 550937 = 551164
353 + 550811 = 551164
401 + 550763 = 551164

Showing the first eight; more decompositions exist.
