Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6606, here are decompositions:
- 7 + 6599 = 6606
- 29 + 6577 = 6606
- 37 + 6569 = 6606
- 43 + 6563 = 6606
- 53 + 6553 = 6606
- 59 + 6547 = 6606
- 137 + 6469 = 6606
- 157 + 6449 = 6606
Showing the first eight; more decompositions exist.
