Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82138, here are decompositions:
- 71 + 82067 = 82138
- 101 + 82037 = 82138
- 107 + 82031 = 82138
- 131 + 82007 = 82138
- 167 + 81971 = 82138
- 239 + 81899 = 82138
- 269 + 81869 = 82138
- 389 + 81749 = 82138
Showing the first eight; more decompositions exist.
