Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1916, here are decompositions:
- 3 + 1913 = 1916
- 37 + 1879 = 1916
- 43 + 1873 = 1916
- 127 + 1789 = 1916
- 139 + 1777 = 1916
- 157 + 1759 = 1916
- 163 + 1753 = 1916
- 193 + 1723 = 1916
Showing the first eight; more decompositions exist.
