Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72724, here are decompositions:
- 5 + 72719 = 72724
- 17 + 72707 = 72724
- 23 + 72701 = 72724
- 53 + 72671 = 72724
- 101 + 72623 = 72724
- 107 + 72617 = 72724
- 173 + 72551 = 72724
- 191 + 72533 = 72724
Showing the first eight; more decompositions exist.
