Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20338, here are decompositions:
- 5 + 20333 = 20338
- 11 + 20327 = 20338
- 41 + 20297 = 20338
- 89 + 20249 = 20338
- 107 + 20231 = 20338
- 137 + 20201 = 20338
- 191 + 20147 = 20338
- 317 + 20021 = 20338
Showing the first eight; more decompositions exist.
