Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549680, here are decompositions:

13 + 549667 = 549680
31 + 549649 = 549680
37 + 549643 = 549680
73 + 549607 = 549680
127 + 549553 = 549680
163 + 549517 = 549680
199 + 549481 = 549680
277 + 549403 = 549680

Showing the first eight; more decompositions exist.
