Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13648, here are decompositions:
- 29 + 13619 = 13648
- 71 + 13577 = 13648
- 149 + 13499 = 13648
- 179 + 13469 = 13648
- 191 + 13457 = 13648
- 197 + 13451 = 13648
- 227 + 13421 = 13648
- 251 + 13397 = 13648
Showing the first eight; more decompositions exist.
