Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15956, here are decompositions:
- 19 + 15937 = 15956
- 37 + 15919 = 15956
- 43 + 15913 = 15956
- 67 + 15889 = 15956
- 79 + 15877 = 15956
- 97 + 15859 = 15956
- 139 + 15817 = 15956
- 223 + 15733 = 15956
Showing the first eight; more decompositions exist.
