Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91824, here are decompositions:
- 11 + 91813 = 91824
- 13 + 91811 = 91824
- 17 + 91807 = 91824
- 23 + 91801 = 91824
- 43 + 91781 = 91824
- 53 + 91771 = 91824
- 67 + 91757 = 91824
- 71 + 91753 = 91824
Showing the first eight; more decompositions exist.
