Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17580, here are decompositions:

7 + 17573 = 17580
11 + 17569 = 17580
29 + 17551 = 17580
41 + 17539 = 17580
61 + 17519 = 17580
71 + 17509 = 17580
83 + 17497 = 17580
89 + 17491 = 17580

Showing the first eight; more decompositions exist.
