Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551420, here are decompositions:

13 + 551407 = 551420
73 + 551347 = 551420
109 + 551311 = 551420
139 + 551281 = 551420
151 + 551269 = 551420
223 + 551197 = 551420
241 + 551179 = 551420
277 + 551143 = 551420

Showing the first eight; more decompositions exist.
