Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82242, here are decompositions:
- 5 + 82237 = 82242
- 11 + 82231 = 82242
- 19 + 82223 = 82242
- 23 + 82219 = 82242
- 53 + 82189 = 82242
- 59 + 82183 = 82242
- 71 + 82171 = 82242
- 79 + 82163 = 82242
Showing the first eight; more decompositions exist.
