Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549440, here are decompositions:

19 + 549421 = 549440
37 + 549403 = 549440
61 + 549379 = 549440
109 + 549331 = 549440
127 + 549313 = 549440
181 + 549259 = 549440
193 + 549247 = 549440
211 + 549229 = 549440

Showing the first eight; more decompositions exist.
