Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24640, here are decompositions:
- 17 + 24623 = 24640
- 29 + 24611 = 24640
- 47 + 24593 = 24640
- 89 + 24551 = 24640
- 107 + 24533 = 24640
- 113 + 24527 = 24640
- 131 + 24509 = 24640
- 167 + 24473 = 24640
Showing the first eight; more decompositions exist.
