Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12936, here are decompositions:
- 13 + 12923 = 12936
- 17 + 12919 = 12936
- 19 + 12917 = 12936
- 29 + 12907 = 12936
- 37 + 12899 = 12936
- 43 + 12893 = 12936
- 47 + 12889 = 12936
- 83 + 12853 = 12936
Showing the first eight; more decompositions exist.
