Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550666, here are decompositions:

3 + 550663 = 550666
5 + 550661 = 550666
29 + 550637 = 550666
59 + 550607 = 550666
89 + 550577 = 550666
113 + 550553 = 550666
197 + 550469 = 550666
227 + 550439 = 550666

Showing the first eight; more decompositions exist.
