Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1888, here are decompositions:
- 11 + 1877 = 1888
- 17 + 1871 = 1888
- 41 + 1847 = 1888
- 101 + 1787 = 1888
- 167 + 1721 = 1888
- 179 + 1709 = 1888
- 191 + 1697 = 1888
- 251 + 1637 = 1888
Showing the first eight; more decompositions exist.
