Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13624, here are decompositions:
- 5 + 13619 = 13624
- 11 + 13613 = 13624
- 47 + 13577 = 13624
- 71 + 13553 = 13624
- 101 + 13523 = 13624
- 137 + 13487 = 13624
- 167 + 13457 = 13624
- 173 + 13451 = 13624
Showing the first eight; more decompositions exist.
