Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72660, here are decompositions:
- 11 + 72649 = 72660
- 13 + 72647 = 72660
- 17 + 72643 = 72660
- 37 + 72623 = 72660
- 43 + 72617 = 72660
- 47 + 72613 = 72660
- 83 + 72577 = 72660
- 101 + 72559 = 72660
Showing the first eight; more decompositions exist.
