Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549208, here are decompositions:

5 + 549203 = 549208
41 + 549167 = 549208
47 + 549161 = 549208
59 + 549149 = 549208
137 + 549071 = 549208
197 + 549011 = 549208
251 + 548957 = 549208
281 + 548927 = 549208

Showing the first eight; more decompositions exist.
