Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551080, here are decompositions:

11 + 551069 = 551080
17 + 551063 = 551080
41 + 551039 = 551080
53 + 551027 = 551080
83 + 550997 = 551080
107 + 550973 = 551080
239 + 550841 = 551080
269 + 550811 = 551080

Showing the first eight; more decompositions exist.
