Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13530, here are decompositions:
- 7 + 13523 = 13530
- 17 + 13513 = 13530
- 31 + 13499 = 13530
- 43 + 13487 = 13530
- 53 + 13477 = 13530
- 61 + 13469 = 13530
- 67 + 13463 = 13530
- 73 + 13457 = 13530
Showing the first eight; more decompositions exist.
