Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20528, here are decompositions:
- 7 + 20521 = 20528
- 19 + 20509 = 20528
- 97 + 20431 = 20528
- 139 + 20389 = 20528
- 181 + 20347 = 20528
- 241 + 20287 = 20528
- 367 + 20161 = 20528
- 379 + 20149 = 20528
Showing the first eight; more decompositions exist.
