Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551354, here are decompositions:

7 + 551347 = 551354
43 + 551311 = 551354
73 + 551281 = 551354
157 + 551197 = 551354
211 + 551143 = 551354
241 + 551113 = 551354
337 + 551017 = 551354
523 + 550831 = 551354

Showing the first eight; more decompositions exist.
