Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82220, here are decompositions:
- 3 + 82217 = 82220
- 13 + 82207 = 82220
- 31 + 82189 = 82220
- 37 + 82183 = 82220
- 67 + 82153 = 82220
- 79 + 82141 = 82220
- 181 + 82039 = 82220
- 199 + 82021 = 82220
Showing the first eight; more decompositions exist.
