Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6912, here are decompositions:
- 5 + 6907 = 6912
- 13 + 6899 = 6912
- 29 + 6883 = 6912
- 41 + 6871 = 6912
- 43 + 6869 = 6912
- 71 + 6841 = 6912
- 79 + 6833 = 6912
- 83 + 6829 = 6912
Showing the first eight; more decompositions exist.
