Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20204, here are decompositions:
- 3 + 20201 = 20204
- 31 + 20173 = 20204
- 43 + 20161 = 20204
- 61 + 20143 = 20204
- 97 + 20107 = 20204
- 103 + 20101 = 20204
- 157 + 20047 = 20204
- 181 + 20023 = 20204
Showing the first eight; more decompositions exist.
