Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549730, here are decompositions:

11 + 549719 = 549730
17 + 549713 = 549730
23 + 549707 = 549730
29 + 549701 = 549730
47 + 549683 = 549730
89 + 549641 = 549730
107 + 549623 = 549730
179 + 549551 = 549730

Showing the first eight; more decompositions exist.
