Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99830, here are decompositions:
- 7 + 99823 = 99830
- 13 + 99817 = 99830
- 37 + 99793 = 99830
- 43 + 99787 = 99830
- 97 + 99733 = 99830
- 109 + 99721 = 99830
- 151 + 99679 = 99830
- 163 + 99667 = 99830
Showing the first eight; more decompositions exist.
