Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549386, here are decompositions:

7 + 549379 = 549386
67 + 549319 = 549386
73 + 549313 = 549386
127 + 549259 = 549386
139 + 549247 = 549386
157 + 549229 = 549386
193 + 549193 = 549386
223 + 549163 = 549386

Showing the first eight; more decompositions exist.
