Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549066, here are decompositions:

29 + 549037 = 549066
43 + 549023 = 549066
47 + 549019 = 549066
53 + 549013 = 549066
103 + 548963 = 549066
109 + 548957 = 549066
113 + 548953 = 549066
139 + 548927 = 549066

Showing the first eight; more decompositions exist.
