Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10720, here are decompositions:
- 11 + 10709 = 10720
- 29 + 10691 = 10720
- 53 + 10667 = 10720
- 89 + 10631 = 10720
- 107 + 10613 = 10720
- 113 + 10607 = 10720
- 131 + 10589 = 10720
- 191 + 10529 = 10720
Showing the first eight; more decompositions exist.
