Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551226, here are decompositions:

7 + 551219 = 551226
19 + 551207 = 551226
29 + 551197 = 551226
47 + 551179 = 551226
83 + 551143 = 551226
97 + 551129 = 551226
113 + 551113 = 551226
127 + 551099 = 551226

Showing the first eight; more decompositions exist.
