Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13604, here are decompositions:
- 7 + 13597 = 13604
- 13 + 13591 = 13604
- 37 + 13567 = 13604
- 67 + 13537 = 13604
- 127 + 13477 = 13604
- 163 + 13441 = 13604
- 193 + 13411 = 13604
- 223 + 13381 = 13604
Showing the first eight; more decompositions exist.
