Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83642, here are decompositions:
- 3 + 83639 = 83642
- 79 + 83563 = 83642
- 193 + 83449 = 83642
- 199 + 83443 = 83642
- 211 + 83431 = 83642
- 241 + 83401 = 83642
- 331 + 83311 = 83642
- 373 + 83269 = 83642
Showing the first eight; more decompositions exist.
