Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1894, here are decompositions:
- 5 + 1889 = 1894
- 17 + 1877 = 1894
- 23 + 1871 = 1894
- 47 + 1847 = 1894
- 71 + 1823 = 1894
- 83 + 1811 = 1894
- 107 + 1787 = 1894
- 173 + 1721 = 1894
Showing the first eight; more decompositions exist.
