Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16624, here are decompositions:
- 5 + 16619 = 16624
- 17 + 16607 = 16624
- 71 + 16553 = 16624
- 131 + 16493 = 16624
- 137 + 16487 = 16624
- 173 + 16451 = 16624
- 191 + 16433 = 16624
- 197 + 16427 = 16624
Showing the first eight; more decompositions exist.
