Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20888, here are decompositions:
- 31 + 20857 = 20888
- 79 + 20809 = 20888
- 139 + 20749 = 20888
- 157 + 20731 = 20888
- 181 + 20707 = 20888
- 277 + 20611 = 20888
- 337 + 20551 = 20888
- 367 + 20521 = 20888
Showing the first eight; more decompositions exist.
