Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549248, here are decompositions:

19 + 549229 = 549248
79 + 549169 = 549248
109 + 549139 = 549248
127 + 549121 = 549248
151 + 549097 = 549248
157 + 549091 = 549248
211 + 549037 = 549248
229 + 549019 = 549248

Showing the first eight; more decompositions exist.
