Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12766, here are decompositions:
- 3 + 12763 = 12766
- 23 + 12743 = 12766
- 53 + 12713 = 12766
- 107 + 12659 = 12766
- 113 + 12653 = 12766
- 197 + 12569 = 12766
- 227 + 12539 = 12766
- 239 + 12527 = 12766
Showing the first eight; more decompositions exist.
