Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1730, here are decompositions:
- 7 + 1723 = 1730
- 31 + 1699 = 1730
- 37 + 1693 = 1730
- 61 + 1669 = 1730
- 67 + 1663 = 1730
- 73 + 1657 = 1730
- 103 + 1627 = 1730
- 109 + 1621 = 1730
Showing the first eight; more decompositions exist.
