Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551366, here are decompositions:

3 + 551363 = 551366
19 + 551347 = 551366
97 + 551269 = 551366
223 + 551143 = 551366
307 + 551059 = 551366
349 + 551017 = 551366
373 + 550993 = 551366
397 + 550969 = 551366

Showing the first eight; more decompositions exist.
