Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 732, here are decompositions:
- 5 + 727 = 732
- 13 + 719 = 732
- 23 + 709 = 732
- 31 + 701 = 732
- 41 + 691 = 732
- 59 + 673 = 732
- 71 + 661 = 732
- 73 + 659 = 732
Showing the first eight; more decompositions exist.
