Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82042, here are decompositions:
- 3 + 82039 = 82042
- 5 + 82037 = 82042
- 11 + 82031 = 82042
- 29 + 82013 = 82042
- 71 + 81971 = 82042
- 89 + 81953 = 82042
- 113 + 81929 = 82042
- 173 + 81869 = 82042
Showing the first eight; more decompositions exist.
