Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12912, here are decompositions:
- 5 + 12907 = 12912
- 13 + 12899 = 12912
- 19 + 12893 = 12912
- 23 + 12889 = 12912
- 59 + 12853 = 12912
- 71 + 12841 = 12912
- 83 + 12829 = 12912
- 89 + 12823 = 12912
Showing the first eight; more decompositions exist.
