Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549242, here are decompositions:

13 + 549229 = 549242
73 + 549169 = 549242
79 + 549163 = 549242
103 + 549139 = 549242
151 + 549091 = 549242
223 + 549019 = 549242
229 + 549013 = 549242
241 + 549001 = 549242

Showing the first eight; more decompositions exist.
