Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551308, here are decompositions:

11 + 551297 = 551308
89 + 551219 = 551308
101 + 551207 = 551308
179 + 551129 = 551308
239 + 551069 = 551308
269 + 551039 = 551308
281 + 551027 = 551308
311 + 550997 = 551308

Showing the first eight; more decompositions exist.
