Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20344, here are decompositions:
- 3 + 20341 = 20344
- 11 + 20333 = 20344
- 17 + 20327 = 20344
- 47 + 20297 = 20344
- 83 + 20261 = 20344
- 113 + 20231 = 20344
- 167 + 20177 = 20344
- 197 + 20147 = 20344
Showing the first eight; more decompositions exist.
