Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551446, here are decompositions:

3 + 551443 = 551446
23 + 551423 = 551446
59 + 551387 = 551446
83 + 551363 = 551446
107 + 551339 = 551446
149 + 551297 = 551446
227 + 551219 = 551446
239 + 551207 = 551446

Showing the first eight; more decompositions exist.
