Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20328, here are decompositions:
- 5 + 20323 = 20328
- 31 + 20297 = 20328
- 41 + 20287 = 20328
- 59 + 20269 = 20328
- 67 + 20261 = 20328
- 79 + 20249 = 20328
- 97 + 20231 = 20328
- 109 + 20219 = 20328
Showing the first eight; more decompositions exist.
