Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91812, here are decompositions:
- 5 + 91807 = 91812
- 11 + 91801 = 91812
- 31 + 91781 = 91812
- 41 + 91771 = 91812
- 59 + 91753 = 91812
- 79 + 91733 = 91812
- 101 + 91711 = 91812
- 109 + 91703 = 91812
Showing the first eight; more decompositions exist.
