Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12446, here are decompositions:
- 13 + 12433 = 12446
- 37 + 12409 = 12446
- 67 + 12379 = 12446
- 73 + 12373 = 12446
- 103 + 12343 = 12446
- 157 + 12289 = 12446
- 193 + 12253 = 12446
- 283 + 12163 = 12446
Showing the first eight; more decompositions exist.
