Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551358, here are decompositions:

11 + 551347 = 551358
19 + 551339 = 551358
37 + 551321 = 551358
47 + 551311 = 551358
61 + 551297 = 551358
89 + 551269 = 551358
127 + 551231 = 551358
139 + 551219 = 551358

Showing the first eight; more decompositions exist.
