Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23158, here are decompositions:
- 41 + 23117 = 23158
- 59 + 23099 = 23158
- 71 + 23087 = 23158
- 101 + 23057 = 23158
- 131 + 23027 = 23158
- 137 + 23021 = 23158
- 197 + 22961 = 23158
- 251 + 22907 = 23158
Showing the first eight; more decompositions exist.
