Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6872, here are decompositions:
- 3 + 6869 = 6872
- 31 + 6841 = 6872
- 43 + 6829 = 6872
- 79 + 6793 = 6872
- 109 + 6763 = 6872
- 139 + 6733 = 6872
- 163 + 6709 = 6872
- 181 + 6691 = 6872
Showing the first eight; more decompositions exist.
