Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20318, here are decompositions:
- 31 + 20287 = 20318
- 157 + 20161 = 20318
- 211 + 20107 = 20318
- 229 + 20089 = 20318
- 271 + 20047 = 20318
- 307 + 20011 = 20318
- 457 + 19861 = 20318
- 499 + 19819 = 20318
Showing the first eight; more decompositions exist.
