Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549738, here are decompositions:

5 + 549733 = 549738
19 + 549719 = 549738
31 + 549707 = 549738
37 + 549701 = 549738
47 + 549691 = 549738
71 + 549667 = 549738
89 + 549649 = 549738
97 + 549641 = 549738

Showing the first eight; more decompositions exist.
