Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549506, here are decompositions:

3 + 549503 = 549506
103 + 549403 = 549506
127 + 549379 = 549506
193 + 549313 = 549506
277 + 549229 = 549506
313 + 549193 = 549506
337 + 549169 = 549506
367 + 549139 = 549506

Showing the first eight; more decompositions exist.
