Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91728, here are decompositions:
- 17 + 91711 = 91728
- 37 + 91691 = 91728
- 89 + 91639 = 91728
- 97 + 91631 = 91728
- 107 + 91621 = 91728
- 137 + 91591 = 91728
- 151 + 91577 = 91728
- 157 + 91571 = 91728
Showing the first eight; more decompositions exist.
