Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551316, here are decompositions:

5 + 551311 = 551316
19 + 551297 = 551316
47 + 551269 = 551316
83 + 551233 = 551316
97 + 551219 = 551316
109 + 551207 = 551316
137 + 551179 = 551316
173 + 551143 = 551316

Showing the first eight; more decompositions exist.
