Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20340, here are decompositions:
- 7 + 20333 = 20340
- 13 + 20327 = 20340
- 17 + 20323 = 20340
- 43 + 20297 = 20340
- 53 + 20287 = 20340
- 71 + 20269 = 20340
- 79 + 20261 = 20340
- 107 + 20233 = 20340
Showing the first eight; more decompositions exist.
