Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66560, here are decompositions:
- 7 + 66553 = 66560
- 19 + 66541 = 66560
- 31 + 66529 = 66560
- 37 + 66523 = 66560
- 61 + 66499 = 66560
- 97 + 66463 = 66560
- 103 + 66457 = 66560
- 157 + 66403 = 66560
Showing the first eight; more decompositions exist.
