Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82012, here are decompositions:
- 3 + 82009 = 82012
- 5 + 82007 = 82012
- 41 + 81971 = 82012
- 59 + 81953 = 82012
- 83 + 81929 = 82012
- 113 + 81899 = 82012
- 173 + 81839 = 82012
- 239 + 81773 = 82012
Showing the first eight; more decompositions exist.
