Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1832, here are decompositions:
- 31 + 1801 = 1832
- 43 + 1789 = 1832
- 73 + 1759 = 1832
- 79 + 1753 = 1832
- 109 + 1723 = 1832
- 139 + 1693 = 1832
- 163 + 1669 = 1832
- 211 + 1621 = 1832
Showing the first eight; more decompositions exist.
