Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 694, here are decompositions:
- 3 + 691 = 694
- 11 + 683 = 694
- 17 + 677 = 694
- 41 + 653 = 694
- 47 + 647 = 694
- 53 + 641 = 694
- 101 + 593 = 694
- 107 + 587 = 694
Showing the first eight; more decompositions exist.
