Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91782, here are decompositions:
- 11 + 91771 = 91782
- 29 + 91753 = 91782
- 71 + 91711 = 91782
- 79 + 91703 = 91782
- 109 + 91673 = 91782
- 151 + 91631 = 91782
- 191 + 91591 = 91782
- 199 + 91583 = 91782
Showing the first eight; more decompositions exist.
