Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82072, here are decompositions:
- 5 + 82067 = 82072
- 41 + 82031 = 82072
- 59 + 82013 = 82072
- 101 + 81971 = 82072
- 173 + 81899 = 82072
- 233 + 81839 = 82072
- 311 + 81761 = 82072
- 383 + 81689 = 82072
Showing the first eight; more decompositions exist.
