Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105158, here are decompositions:
- 61 + 105097 = 105158
- 127 + 105031 = 105158
- 139 + 105019 = 105158
- 199 + 104959 = 105158
- 211 + 104947 = 105158
- 241 + 104917 = 105158
- 307 + 104851 = 105158
- 331 + 104827 = 105158
Showing the first eight; more decompositions exist.
