Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13608, here are decompositions:
- 11 + 13597 = 13608
- 17 + 13591 = 13608
- 31 + 13577 = 13608
- 41 + 13567 = 13608
- 71 + 13537 = 13608
- 109 + 13499 = 13608
- 131 + 13477 = 13608
- 139 + 13469 = 13608
Showing the first eight; more decompositions exist.
