Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549278, here are decompositions:

19 + 549259 = 549278
31 + 549247 = 549278
109 + 549169 = 549278
139 + 549139 = 549278
157 + 549121 = 549278
181 + 549097 = 549278
241 + 549037 = 549278
277 + 549001 = 549278

Showing the first eight; more decompositions exist.
