Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72732, here are decompositions:
- 5 + 72727 = 72732
- 13 + 72719 = 72732
- 31 + 72701 = 72732
- 43 + 72689 = 72732
- 53 + 72679 = 72732
- 59 + 72673 = 72732
- 61 + 72671 = 72732
- 71 + 72661 = 72732
Showing the first eight; more decompositions exist.
