Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1922, here are decompositions:
- 43 + 1879 = 1922
- 61 + 1861 = 1922
- 139 + 1783 = 1922
- 163 + 1759 = 1922
- 181 + 1741 = 1922
- 199 + 1723 = 1922
- 223 + 1699 = 1922
- 229 + 1693 = 1922
Showing the first eight; more decompositions exist.
