Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551390, here are decompositions:

3 + 551387 = 551390
43 + 551347 = 551390
79 + 551311 = 551390
109 + 551281 = 551390
157 + 551233 = 551390
193 + 551197 = 551390
211 + 551179 = 551390
277 + 551113 = 551390

Showing the first eight; more decompositions exist.
