Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549326, here are decompositions:

3 + 549323 = 549326
7 + 549319 = 549326
13 + 549313 = 549326
67 + 549259 = 549326
79 + 549247 = 549326
97 + 549229 = 549326
157 + 549169 = 549326
163 + 549163 = 549326

Showing the first eight; more decompositions exist.
