Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17680, here are decompositions:

11 + 17669 = 17680
23 + 17657 = 17680
53 + 17627 = 17680
71 + 17609 = 17680
83 + 17597 = 17680
101 + 17579 = 17680
107 + 17573 = 17680
191 + 17489 = 17680

Showing the first eight; more decompositions exist.
