Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551184, here are decompositions:

5 + 551179 = 551184
41 + 551143 = 551184
71 + 551113 = 551184
157 + 551027 = 551184
167 + 551017 = 551184
181 + 551003 = 551184
191 + 550993 = 551184
211 + 550973 = 551184

Showing the first eight; more decompositions exist.
