Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72736, here are decompositions:
- 3 + 72733 = 72736
- 17 + 72719 = 72736
- 29 + 72707 = 72736
- 47 + 72689 = 72736
- 89 + 72647 = 72736
- 113 + 72623 = 72736
- 233 + 72503 = 72736
- 239 + 72497 = 72736
Showing the first eight; more decompositions exist.
