Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549640, here are decompositions:

17 + 549623 = 549640
53 + 549587 = 549640
71 + 549569 = 549640
89 + 549551 = 549640
107 + 549533 = 549640
131 + 549509 = 549640
137 + 549503 = 549640
191 + 549449 = 549640

Showing the first eight; more decompositions exist.
