Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89878, here are decompositions:
- 11 + 89867 = 89878
- 29 + 89849 = 89878
- 59 + 89819 = 89878
- 197 + 89681 = 89878
- 251 + 89627 = 89878
- 281 + 89597 = 89878
- 311 + 89567 = 89878
- 317 + 89561 = 89878
Showing the first eight; more decompositions exist.
