Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1874, here are decompositions:
- 3 + 1871 = 1874
- 7 + 1867 = 1874
- 13 + 1861 = 1874
- 43 + 1831 = 1874
- 73 + 1801 = 1874
- 97 + 1777 = 1874
- 127 + 1747 = 1874
- 151 + 1723 = 1874
Showing the first eight; more decompositions exist.
