Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20048, here are decompositions:
- 19 + 20029 = 20048
- 37 + 20011 = 20048
- 157 + 19891 = 20048
- 181 + 19867 = 20048
- 229 + 19819 = 20048
- 271 + 19777 = 20048
- 331 + 19717 = 20048
- 349 + 19699 = 20048
Showing the first eight; more decompositions exist.
