Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551718, here are decompositions:

5 + 551713 = 551718
29 + 551689 = 551718
47 + 551671 = 551718
59 + 551659 = 551718
67 + 551651 = 551718
131 + 551587 = 551718
137 + 551581 = 551718
149 + 551569 = 551718

Showing the first eight; more decompositions exist.
