Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23428, here are decompositions:
- 11 + 23417 = 23428
- 29 + 23399 = 23428
- 59 + 23369 = 23428
- 71 + 23357 = 23428
- 89 + 23339 = 23428
- 101 + 23327 = 23428
- 107 + 23321 = 23428
- 131 + 23297 = 23428
Showing the first eight; more decompositions exist.
