Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91740, here are decompositions:
- 7 + 91733 = 91740
- 29 + 91711 = 91740
- 37 + 91703 = 91740
- 67 + 91673 = 91740
- 101 + 91639 = 91740
- 109 + 91631 = 91740
- 149 + 91591 = 91740
- 157 + 91583 = 91740
Showing the first eight; more decompositions exist.
