Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82642, here are decompositions:
- 23 + 82619 = 82642
- 29 + 82613 = 82642
- 41 + 82601 = 82642
- 71 + 82571 = 82642
- 83 + 82559 = 82642
- 113 + 82529 = 82642
- 149 + 82493 = 82642
- 173 + 82469 = 82642
Showing the first eight; more decompositions exist.
