Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28342, here are decompositions:
- 23 + 28319 = 28342
- 53 + 28289 = 28342
- 59 + 28283 = 28342
- 113 + 28229 = 28342
- 131 + 28211 = 28342
- 179 + 28163 = 28342
- 191 + 28151 = 28342
- 233 + 28109 = 28342
Showing the first eight; more decompositions exist.
