Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549162, here are decompositions:

13 + 549149 = 549162
23 + 549139 = 549162
41 + 549121 = 549162
71 + 549091 = 549162
73 + 549089 = 549162
139 + 549023 = 549162
149 + 549013 = 549162
151 + 549011 = 549162

Showing the first eight; more decompositions exist.
