Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20028, here are decompositions:
- 5 + 20023 = 20028
- 7 + 20021 = 20028
- 17 + 20011 = 20028
- 31 + 19997 = 20028
- 37 + 19991 = 20028
- 67 + 19961 = 20028
- 79 + 19949 = 20028
- 101 + 19927 = 20028
Showing the first eight; more decompositions exist.
