Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549418, here are decompositions:

137 + 549281 = 549418
197 + 549221 = 549418
251 + 549167 = 549418
257 + 549161 = 549418
269 + 549149 = 549418
347 + 549071 = 549418
461 + 548957 = 549418
491 + 548927 = 549418

Showing the first eight; more decompositions exist.
