Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20194, here are decompositions:
- 11 + 20183 = 20194
- 17 + 20177 = 20194
- 47 + 20147 = 20194
- 71 + 20123 = 20194
- 131 + 20063 = 20194
- 173 + 20021 = 20194
- 197 + 19997 = 20194
- 233 + 19961 = 20194
Showing the first eight; more decompositions exist.
