Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1748, here are decompositions:
- 7 + 1741 = 1748
- 79 + 1669 = 1748
- 127 + 1621 = 1748
- 139 + 1609 = 1748
- 151 + 1597 = 1748
- 181 + 1567 = 1748
- 199 + 1549 = 1748
- 277 + 1471 = 1748
Showing the first eight; more decompositions exist.
