Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549358, here are decompositions:

101 + 549257 = 549358
137 + 549221 = 549358
191 + 549167 = 549358
197 + 549161 = 549358
269 + 549089 = 549358
347 + 549011 = 549358
401 + 548957 = 549358
431 + 548927 = 549358

Showing the first eight; more decompositions exist.
