Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1670, here are decompositions:
- 3 + 1667 = 1670
- 7 + 1663 = 1670
- 13 + 1657 = 1670
- 43 + 1627 = 1670
- 61 + 1609 = 1670
- 73 + 1597 = 1670
- 103 + 1567 = 1670
- 127 + 1543 = 1670
Showing the first eight; more decompositions exist.
