Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6600, here are decompositions:
- 19 + 6581 = 6600
- 23 + 6577 = 6600
- 29 + 6571 = 6600
- 31 + 6569 = 6600
- 37 + 6563 = 6600
- 47 + 6553 = 6600
- 53 + 6547 = 6600
- 71 + 6529 = 6600
Showing the first eight; more decompositions exist.
