Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551422, here are decompositions:

41 + 551381 = 551422
59 + 551363 = 551422
83 + 551339 = 551422
101 + 551321 = 551422
191 + 551231 = 551422
293 + 551129 = 551422
353 + 551069 = 551422
359 + 551063 = 551422

Showing the first eight; more decompositions exist.
