Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549540, here are decompositions:

7 + 549533 = 549540
23 + 549517 = 549540
29 + 549511 = 549540
31 + 549509 = 549540
37 + 549503 = 549540
59 + 549481 = 549540
97 + 549443 = 549540
109 + 549431 = 549540

Showing the first eight; more decompositions exist.
