Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549530, here are decompositions:

13 + 549517 = 549530
19 + 549511 = 549530
109 + 549421 = 549530
127 + 549403 = 549530
139 + 549391 = 549530
151 + 549379 = 549530
199 + 549331 = 549530
211 + 549319 = 549530

Showing the first eight; more decompositions exist.
