Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551028, here are decompositions:

11 + 551017 = 551028
31 + 550997 = 551028
59 + 550969 = 551028
67 + 550961 = 551028
89 + 550939 = 551028
167 + 550861 = 551028
197 + 550831 = 551028
227 + 550801 = 551028

Showing the first eight; more decompositions exist.
