Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549500, here are decompositions:

19 + 549481 = 549500
79 + 549421 = 549500
97 + 549403 = 549500
109 + 549391 = 549500
181 + 549319 = 549500
241 + 549259 = 549500
271 + 549229 = 549500
307 + 549193 = 549500

Showing the first eight; more decompositions exist.
