Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12624, here are decompositions:
- 5 + 12619 = 12624
- 11 + 12613 = 12624
- 13 + 12611 = 12624
- 23 + 12601 = 12624
- 41 + 12583 = 12624
- 47 + 12577 = 12624
- 71 + 12553 = 12624
- 83 + 12541 = 12624
Showing the first eight; more decompositions exist.
