Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549404, here are decompositions:

13 + 549391 = 549404
73 + 549331 = 549404
157 + 549247 = 549404
211 + 549193 = 549404
241 + 549163 = 549404
283 + 549121 = 549404
307 + 549097 = 549404
313 + 549091 = 549404

Showing the first eight; more decompositions exist.
