Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551686, here are decompositions:

89 + 551597 = 551686
137 + 551549 = 551686
167 + 551519 = 551686
197 + 551489 = 551686
263 + 551423 = 551686
347 + 551339 = 551686
389 + 551297 = 551686
467 + 551219 = 551686

Showing the first eight; more decompositions exist.
