Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549372, here are decompositions:

41 + 549331 = 549372
53 + 549319 = 549372
59 + 549313 = 549372
113 + 549259 = 549372
151 + 549221 = 549372
179 + 549193 = 549372
211 + 549161 = 549372
223 + 549149 = 549372

Showing the first eight; more decompositions exist.
