Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13506, here are decompositions:
- 7 + 13499 = 13506
- 19 + 13487 = 13506
- 29 + 13477 = 13506
- 37 + 13469 = 13506
- 43 + 13463 = 13506
- 89 + 13417 = 13506
- 107 + 13399 = 13506
- 109 + 13397 = 13506
Showing the first eight; more decompositions exist.
