Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82120, here are decompositions:
- 47 + 82073 = 82120
- 53 + 82067 = 82120
- 83 + 82037 = 82120
- 89 + 82031 = 82120
- 107 + 82013 = 82120
- 113 + 82007 = 82120
- 149 + 81971 = 82120
- 167 + 81953 = 82120
Showing the first eight; more decompositions exist.
