Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1674, here are decompositions:
- 5 + 1669 = 1674
- 7 + 1667 = 1674
- 11 + 1663 = 1674
- 17 + 1657 = 1674
- 37 + 1637 = 1674
- 47 + 1627 = 1674
- 53 + 1621 = 1674
- 61 + 1613 = 1674
Showing the first eight; more decompositions exist.
