Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20588, here are decompositions:
- 37 + 20551 = 20588
- 67 + 20521 = 20588
- 79 + 20509 = 20588
- 109 + 20479 = 20588
- 157 + 20431 = 20588
- 181 + 20407 = 20588
- 199 + 20389 = 20588
- 229 + 20359 = 20588
Showing the first eight; more decompositions exist.
