Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1634, here are decompositions:
- 7 + 1627 = 1634
- 13 + 1621 = 1634
- 37 + 1597 = 1634
- 67 + 1567 = 1634
- 103 + 1531 = 1634
- 151 + 1483 = 1634
- 163 + 1471 = 1634
- 181 + 1453 = 1634
Showing the first eight; more decompositions exist.
