Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1798, here are decompositions:
- 11 + 1787 = 1798
- 89 + 1709 = 1798
- 101 + 1697 = 1798
- 131 + 1667 = 1798
- 179 + 1619 = 1798
- 191 + 1607 = 1798
- 197 + 1601 = 1798
- 227 + 1571 = 1798
Showing the first eight; more decompositions exist.
