Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40258, here are decompositions:
- 5 + 40253 = 40258
- 17 + 40241 = 40258
- 89 + 40169 = 40258
- 107 + 40151 = 40258
- 131 + 40127 = 40258
- 227 + 40031 = 40258
- 269 + 39989 = 40258
- 389 + 39869 = 40258
Showing the first eight; more decompositions exist.
