Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1756, here are decompositions:
- 3 + 1753 = 1756
- 23 + 1733 = 1756
- 47 + 1709 = 1756
- 59 + 1697 = 1756
- 89 + 1667 = 1756
- 137 + 1619 = 1756
- 149 + 1607 = 1756
- 173 + 1583 = 1756
Showing the first eight; more decompositions exist.
