Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105920, here are decompositions:
- 7 + 105913 = 105920
- 13 + 105907 = 105920
- 37 + 105883 = 105920
- 103 + 105817 = 105920
- 151 + 105769 = 105920
- 193 + 105727 = 105920
- 229 + 105691 = 105920
- 271 + 105649 = 105920
Showing the first eight; more decompositions exist.
