Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1718, here are decompositions:
- 19 + 1699 = 1718
- 61 + 1657 = 1718
- 97 + 1621 = 1718
- 109 + 1609 = 1718
- 139 + 1579 = 1718
- 151 + 1567 = 1718
- 229 + 1489 = 1718
- 271 + 1447 = 1718
Showing the first eight; more decompositions exist.
