Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 748, here are decompositions:
- 5 + 743 = 748
- 29 + 719 = 748
- 47 + 701 = 748
- 71 + 677 = 748
- 89 + 659 = 748
- 101 + 647 = 748
- 107 + 641 = 748
- 131 + 617 = 748
Showing the first eight; more decompositions exist.
