Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20306, here are decompositions:
- 19 + 20287 = 20306
- 37 + 20269 = 20306
- 73 + 20233 = 20306
- 157 + 20149 = 20306
- 163 + 20143 = 20306
- 193 + 20113 = 20306
- 199 + 20107 = 20306
- 277 + 20029 = 20306
Showing the first eight; more decompositions exist.
