Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105998, here are decompositions:
- 31 + 105967 = 105998
- 127 + 105871 = 105998
- 181 + 105817 = 105998
- 229 + 105769 = 105998
- 271 + 105727 = 105998
- 307 + 105691 = 105998
- 331 + 105667 = 105998
- 349 + 105649 = 105998
Showing the first eight; more decompositions exist.
