Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549078, here are decompositions:

7 + 549071 = 549078
41 + 549037 = 549078
59 + 549019 = 549078
67 + 549011 = 549078
151 + 548927 = 549078
181 + 548897 = 549078
227 + 548851 = 549078
241 + 548837 = 549078

Showing the first eight; more decompositions exist.
