Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86724, here are decompositions:
- 5 + 86719 = 86724
- 13 + 86711 = 86724
- 31 + 86693 = 86724
- 47 + 86677 = 86724
- 97 + 86627 = 86724
- 137 + 86587 = 86724
- 151 + 86573 = 86724
- 163 + 86561 = 86724
Showing the first eight; more decompositions exist.
