Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13378, here are decompositions:
- 11 + 13367 = 13378
- 41 + 13337 = 13378
- 47 + 13331 = 13378
- 137 + 13241 = 13378
- 149 + 13229 = 13378
- 191 + 13187 = 13378
- 227 + 13151 = 13378
- 251 + 13127 = 13378
Showing the first eight; more decompositions exist.
