Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3956, here are decompositions:
- 13 + 3943 = 3956
- 37 + 3919 = 3956
- 67 + 3889 = 3956
- 79 + 3877 = 3956
- 103 + 3853 = 3956
- 109 + 3847 = 3956
- 163 + 3793 = 3956
- 223 + 3733 = 3956
Showing the first eight; more decompositions exist.
