Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17730, here are decompositions:

17 + 17713 = 17730
23 + 17707 = 17730
47 + 17683 = 17730
61 + 17669 = 17730
71 + 17659 = 17730
73 + 17657 = 17730
103 + 17627 = 17730
107 + 17623 = 17730

Showing the first eight; more decompositions exist.
