Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551086, here are decompositions:

17 + 551069 = 551086
23 + 551063 = 551086
47 + 551039 = 551086
59 + 551027 = 551086
83 + 551003 = 551086
89 + 550997 = 551086
113 + 550973 = 551086
149 + 550937 = 551086

Showing the first eight; more decompositions exist.
