Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549018, here are decompositions:

5 + 549013 = 549018
7 + 549011 = 549018
17 + 549001 = 549018
61 + 548957 = 549018
109 + 548909 = 549018
149 + 548869 = 549018
157 + 548861 = 549018
167 + 548851 = 549018

Showing the first eight; more decompositions exist.
