Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12992, here are decompositions:
- 13 + 12979 = 12992
- 19 + 12973 = 12992
- 73 + 12919 = 12992
- 103 + 12889 = 12992
- 139 + 12853 = 12992
- 151 + 12841 = 12992
- 163 + 12829 = 12992
- 193 + 12799 = 12992
Showing the first eight; more decompositions exist.
