Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6624, here are decompositions:
- 5 + 6619 = 6624
- 17 + 6607 = 6624
- 43 + 6581 = 6624
- 47 + 6577 = 6624
- 53 + 6571 = 6624
- 61 + 6563 = 6624
- 71 + 6553 = 6624
- 73 + 6551 = 6624
Showing the first eight; more decompositions exist.
