Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91840, here are decompositions:
- 3 + 91837 = 91840
- 17 + 91823 = 91840
- 29 + 91811 = 91840
- 59 + 91781 = 91840
- 83 + 91757 = 91840
- 107 + 91733 = 91840
- 137 + 91703 = 91840
- 149 + 91691 = 91840
Showing the first eight; more decompositions exist.
