Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551470, here are decompositions:

47 + 551423 = 551470
83 + 551387 = 551470
89 + 551381 = 551470
107 + 551363 = 551470
131 + 551339 = 551470
149 + 551321 = 551470
173 + 551297 = 551470
239 + 551231 = 551470

Showing the first eight; more decompositions exist.
