Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 744, here are decompositions:
- 5 + 739 = 744
- 11 + 733 = 744
- 17 + 727 = 744
- 43 + 701 = 744
- 53 + 691 = 744
- 61 + 683 = 744
- 67 + 677 = 744
- 71 + 673 = 744
Showing the first eight; more decompositions exist.
