Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16830, here are decompositions:
- 7 + 16823 = 16830
- 19 + 16811 = 16830
- 43 + 16787 = 16830
- 67 + 16763 = 16830
- 71 + 16759 = 16830
- 83 + 16747 = 16830
- 89 + 16741 = 16830
- 101 + 16729 = 16830
Showing the first eight; more decompositions exist.
