Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551278, here are decompositions:

47 + 551231 = 551278
59 + 551219 = 551278
71 + 551207 = 551278
149 + 551129 = 551278
179 + 551099 = 551278
239 + 551039 = 551278
251 + 551027 = 551278
281 + 550997 = 551278

Showing the first eight; more decompositions exist.
