Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551558, here are decompositions:

19 + 551539 = 551558
97 + 551461 = 551558
151 + 551407 = 551558
211 + 551347 = 551558
277 + 551281 = 551558
379 + 551179 = 551558
499 + 551059 = 551558
541 + 551017 = 551558

Showing the first eight; more decompositions exist.
