Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91830, here are decompositions:
- 7 + 91823 = 91830
- 17 + 91813 = 91830
- 19 + 91811 = 91830
- 23 + 91807 = 91830
- 29 + 91801 = 91830
- 59 + 91771 = 91830
- 73 + 91757 = 91830
- 97 + 91733 = 91830
Showing the first eight; more decompositions exist.
