Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549258, here are decompositions:

11 + 549247 = 549258
29 + 549229 = 549258
37 + 549221 = 549258
89 + 549169 = 549258
97 + 549161 = 549258
109 + 549149 = 549258
137 + 549121 = 549258
167 + 549091 = 549258

Showing the first eight; more decompositions exist.
