Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6672, here are decompositions:
- 11 + 6661 = 6672
- 13 + 6659 = 6672
- 19 + 6653 = 6672
- 53 + 6619 = 6672
- 73 + 6599 = 6672
- 101 + 6571 = 6672
- 103 + 6569 = 6672
- 109 + 6563 = 6672
Showing the first eight; more decompositions exist.
