Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551406, here are decompositions:

19 + 551387 = 551406
43 + 551363 = 551406
59 + 551347 = 551406
67 + 551339 = 551406
109 + 551297 = 551406
137 + 551269 = 551406
173 + 551233 = 551406
199 + 551207 = 551406

Showing the first eight; more decompositions exist.
