Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171730, here are decompositions:

11 + 171719 = 171730
17 + 171713 = 171730
23 + 171707 = 171730
59 + 171671 = 171730
71 + 171659 = 171730
89 + 171641 = 171730
101 + 171629 = 171730
113 + 171617 = 171730

Showing the first eight; more decompositions exist.
