Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549428, here are decompositions:

7 + 549421 = 549428
37 + 549391 = 549428
97 + 549331 = 549428
109 + 549319 = 549428
181 + 549247 = 549428
199 + 549229 = 549428
307 + 549121 = 549428
331 + 549097 = 549428

Showing the first eight; more decompositions exist.
