Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13670, here are decompositions:
- 37 + 13633 = 13670
- 43 + 13627 = 13670
- 73 + 13597 = 13670
- 79 + 13591 = 13670
- 103 + 13567 = 13670
- 157 + 13513 = 13670
- 193 + 13477 = 13670
- 229 + 13441 = 13670
Showing the first eight; more decompositions exist.
