Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551328, here are decompositions:

7 + 551321 = 551328
17 + 551311 = 551328
31 + 551297 = 551328
47 + 551281 = 551328
59 + 551269 = 551328
97 + 551231 = 551328
109 + 551219 = 551328
131 + 551197 = 551328

Showing the first eight; more decompositions exist.
