Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551346, here are decompositions:

7 + 551339 = 551346
113 + 551233 = 551346
127 + 551219 = 551346
139 + 551207 = 551346
149 + 551197 = 551346
167 + 551179 = 551346
233 + 551113 = 551346
239 + 551107 = 551346

Showing the first eight; more decompositions exist.
