Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20342, here are decompositions:
- 19 + 20323 = 20342
- 73 + 20269 = 20342
- 109 + 20233 = 20342
- 181 + 20161 = 20342
- 193 + 20149 = 20342
- 199 + 20143 = 20342
- 229 + 20113 = 20342
- 241 + 20101 = 20342
Showing the first eight; more decompositions exist.
