Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12904, here are decompositions:
- 5 + 12899 = 12904
- 11 + 12893 = 12904
- 83 + 12821 = 12904
- 113 + 12791 = 12904
- 191 + 12713 = 12904
- 233 + 12671 = 12904
- 251 + 12653 = 12904
- 257 + 12647 = 12904
Showing the first eight; more decompositions exist.
