Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551068, here are decompositions:

5 + 551063 = 551068
29 + 551039 = 551068
41 + 551027 = 551068
71 + 550997 = 551068
107 + 550961 = 551068
131 + 550937 = 551068
227 + 550841 = 551068
257 + 550811 = 551068

Showing the first eight; more decompositions exist.
