Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1790, here are decompositions:
- 3 + 1787 = 1790
- 7 + 1783 = 1790
- 13 + 1777 = 1790
- 31 + 1759 = 1790
- 37 + 1753 = 1790
- 43 + 1747 = 1790
- 67 + 1723 = 1790
- 97 + 1693 = 1790
Showing the first eight; more decompositions exist.
