Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 766, here are decompositions:
- 5 + 761 = 766
- 23 + 743 = 766
- 47 + 719 = 766
- 83 + 683 = 766
- 89 + 677 = 766
- 107 + 659 = 766
- 113 + 653 = 766
- 149 + 617 = 766
Showing the first eight; more decompositions exist.
