Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549458, here are decompositions:

37 + 549421 = 549458
67 + 549391 = 549458
79 + 549379 = 549458
127 + 549331 = 549458
139 + 549319 = 549458
199 + 549259 = 549458
211 + 549247 = 549458
229 + 549229 = 549458

Showing the first eight; more decompositions exist.
