Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 746, here are decompositions:
- 3 + 743 = 746
- 7 + 739 = 746
- 13 + 733 = 746
- 19 + 727 = 746
- 37 + 709 = 746
- 73 + 673 = 746
- 103 + 643 = 746
- 127 + 619 = 746
Showing the first eight; more decompositions exist.
