Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549580, here are decompositions:

11 + 549569 = 549580
29 + 549551 = 549580
47 + 549533 = 549580
71 + 549509 = 549580
131 + 549449 = 549580
137 + 549443 = 549580
149 + 549431 = 549580
257 + 549323 = 549580

Showing the first eight; more decompositions exist.
