Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1826, here are decompositions:
- 3 + 1823 = 1826
- 37 + 1789 = 1826
- 43 + 1783 = 1826
- 67 + 1759 = 1826
- 73 + 1753 = 1826
- 79 + 1747 = 1826
- 103 + 1723 = 1826
- 127 + 1699 = 1826
Showing the first eight; more decompositions exist.
