Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13216, here are decompositions:
- 29 + 13187 = 13216
- 53 + 13163 = 13216
- 89 + 13127 = 13216
- 107 + 13109 = 13216
- 113 + 13103 = 13216
- 167 + 13049 = 13216
- 173 + 13043 = 13216
- 179 + 13037 = 13216
Showing the first eight; more decompositions exist.
