Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551084, here are decompositions:

67 + 551017 = 551084
181 + 550903 = 551084
223 + 550861 = 551084
241 + 550843 = 551084
271 + 550813 = 551084
283 + 550801 = 551084
367 + 550717 = 551084
421 + 550663 = 551084

Showing the first eight; more decompositions exist.
