Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105894, here are decompositions:
- 11 + 105883 = 105894
- 23 + 105871 = 105894
- 31 + 105863 = 105894
- 127 + 105767 = 105894
- 167 + 105727 = 105894
- 193 + 105701 = 105894
- 211 + 105683 = 105894
- 227 + 105667 = 105894
Showing the first eight; more decompositions exist.
