Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1632, here are decompositions:
- 5 + 1627 = 1632
- 11 + 1621 = 1632
- 13 + 1619 = 1632
- 19 + 1613 = 1632
- 23 + 1609 = 1632
- 31 + 1601 = 1632
- 53 + 1579 = 1632
- 61 + 1571 = 1632
Showing the first eight; more decompositions exist.
