Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549400, here are decompositions:

179 + 549221 = 549400
197 + 549203 = 549400
233 + 549167 = 549400
239 + 549161 = 549400
251 + 549149 = 549400
311 + 549089 = 549400
389 + 549011 = 549400
443 + 548957 = 549400

Showing the first eight; more decompositions exist.
