Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549028, here are decompositions:

5 + 549023 = 549028
17 + 549011 = 549028
71 + 548957 = 549028
101 + 548927 = 549028
131 + 548897 = 549028
167 + 548861 = 549028
191 + 548837 = 549028
197 + 548831 = 549028

Showing the first eight; more decompositions exist.
