Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551288, here are decompositions:

7 + 551281 = 551288
19 + 551269 = 551288
109 + 551179 = 551288
181 + 551107 = 551288
229 + 551059 = 551288
271 + 551017 = 551288
337 + 550951 = 551288
349 + 550939 = 551288

Showing the first eight; more decompositions exist.
