Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551966, here are decompositions:

3 + 551963 = 551966
7 + 551959 = 551966
157 + 551809 = 551966
193 + 551773 = 551966
199 + 551767 = 551966
223 + 551743 = 551966
277 + 551689 = 551966
307 + 551659 = 551966

Showing the first eight; more decompositions exist.
