Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551426, here are decompositions:

3 + 551423 = 551426
19 + 551407 = 551426
79 + 551347 = 551426
157 + 551269 = 551426
193 + 551233 = 551426
229 + 551197 = 551426
283 + 551143 = 551426
313 + 551113 = 551426

Showing the first eight; more decompositions exist.
