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.
