Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 676, here are decompositions:
- 3 + 673 = 676
- 17 + 659 = 676
- 23 + 653 = 676
- 29 + 647 = 676
- 59 + 617 = 676
- 83 + 593 = 676
- 89 + 587 = 676
- 107 + 569 = 676
Showing the first eight; more decompositions exist.
