Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549288, here are decompositions:

7 + 549281 = 549288
29 + 549259 = 549288
31 + 549257 = 549288
41 + 549247 = 549288
59 + 549229 = 549288
67 + 549221 = 549288
127 + 549161 = 549288
139 + 549149 = 549288

Showing the first eight; more decompositions exist.
