Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 696, here are decompositions:
- 5 + 691 = 696
- 13 + 683 = 696
- 19 + 677 = 696
- 23 + 673 = 696
- 37 + 659 = 696
- 43 + 653 = 696
- 53 + 643 = 696
- 79 + 617 = 696
Showing the first eight; more decompositions exist.
