Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550660, here are decompositions:

3 + 550657 = 550660
23 + 550637 = 550660
29 + 550631 = 550660
53 + 550607 = 550660
83 + 550577 = 550660
107 + 550553 = 550660
191 + 550469 = 550660
233 + 550427 = 550660

Showing the first eight; more decompositions exist.
