Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82212, here are decompositions:
- 5 + 82207 = 82212
- 19 + 82193 = 82212
- 23 + 82189 = 82212
- 29 + 82183 = 82212
- 41 + 82171 = 82212
- 59 + 82153 = 82212
- 71 + 82141 = 82212
- 73 + 82139 = 82212
Showing the first eight; more decompositions exist.
