Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551396, here are decompositions:

127 + 551269 = 551396
163 + 551233 = 551396
199 + 551197 = 551396
283 + 551113 = 551396
337 + 551059 = 551396
379 + 551017 = 551396
457 + 550939 = 551396
487 + 550909 = 551396

Showing the first eight; more decompositions exist.
