Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549126, here are decompositions:

5 + 549121 = 549126
29 + 549097 = 549126
37 + 549089 = 549126
89 + 549037 = 549126
103 + 549023 = 549126
107 + 549019 = 549126
113 + 549013 = 549126
163 + 548963 = 549126

Showing the first eight; more decompositions exist.
