Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549138, here are decompositions:

17 + 549121 = 549138
41 + 549097 = 549138
47 + 549091 = 549138
67 + 549071 = 549138
101 + 549037 = 549138
127 + 549011 = 549138
137 + 549001 = 549138
181 + 548957 = 549138

Showing the first eight; more decompositions exist.
