Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550918, here are decompositions:

59 + 550859 = 550918
107 + 550811 = 550918
197 + 550721 = 550918
227 + 550691 = 550918
239 + 550679 = 550918
257 + 550661 = 550918
281 + 550637 = 550918
311 + 550607 = 550918

Showing the first eight; more decompositions exist.
