Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13412, here are decompositions:
- 13 + 13399 = 13412
- 31 + 13381 = 13412
- 73 + 13339 = 13412
- 103 + 13309 = 13412
- 163 + 13249 = 13412
- 193 + 13219 = 13412
- 229 + 13183 = 13412
- 241 + 13171 = 13412
Showing the first eight; more decompositions exist.
