Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551456, here are decompositions:

13 + 551443 = 551456
109 + 551347 = 551456
223 + 551233 = 551456
277 + 551179 = 551456
313 + 551143 = 551456
349 + 551107 = 551456
397 + 551059 = 551456
439 + 551017 = 551456

Showing the first eight; more decompositions exist.
