Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551386, here are decompositions:

5 + 551381 = 551386
23 + 551363 = 551386
47 + 551339 = 551386
89 + 551297 = 551386
167 + 551219 = 551386
179 + 551207 = 551386
257 + 551129 = 551386
293 + 551093 = 551386

Showing the first eight; more decompositions exist.
