Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12902, here are decompositions:
- 3 + 12899 = 12902
- 13 + 12889 = 12902
- 61 + 12841 = 12902
- 73 + 12829 = 12902
- 79 + 12823 = 12902
- 103 + 12799 = 12902
- 139 + 12763 = 12902
- 163 + 12739 = 12902
Showing the first eight; more decompositions exist.
