Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549030, here are decompositions:

7 + 549023 = 549030
11 + 549019 = 549030
17 + 549013 = 549030
19 + 549011 = 549030
29 + 549001 = 549030
67 + 548963 = 549030
73 + 548957 = 549030
103 + 548927 = 549030

Showing the first eight; more decompositions exist.
