Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1738, here are decompositions:
- 5 + 1733 = 1738
- 17 + 1721 = 1738
- 29 + 1709 = 1738
- 41 + 1697 = 1738
- 71 + 1667 = 1738
- 101 + 1637 = 1738
- 131 + 1607 = 1738
- 137 + 1601 = 1738
Showing the first eight; more decompositions exist.
