Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 830, here are decompositions:
- 3 + 827 = 830
- 7 + 823 = 830
- 19 + 811 = 830
- 43 + 787 = 830
- 61 + 769 = 830
- 73 + 757 = 830
- 79 + 751 = 830
- 97 + 733 = 830
Showing the first eight; more decompositions exist.
