Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551928, here are decompositions:

11 + 551917 = 551928
17 + 551911 = 551928
19 + 551909 = 551928
67 + 551861 = 551928
79 + 551849 = 551928
127 + 551801 = 551928
197 + 551731 = 551928
199 + 551729 = 551928

Showing the first eight; more decompositions exist.
