Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99878, here are decompositions:
- 7 + 99871 = 99878
- 19 + 99859 = 99878
- 61 + 99817 = 99878
- 157 + 99721 = 99878
- 199 + 99679 = 99878
- 211 + 99667 = 99878
- 271 + 99607 = 99878
- 307 + 99571 = 99878
Showing the first eight; more decompositions exist.
