Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549928, here are decompositions:

17 + 549911 = 549928
89 + 549839 = 549928
179 + 549749 = 549928
191 + 549737 = 549928
227 + 549701 = 549928
359 + 549569 = 549928
419 + 549509 = 549928
479 + 549449 = 549928

Showing the first eight; more decompositions exist.
