Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992, here are decompositions:
- 73 + 919 = 992
- 109 + 883 = 992
- 139 + 853 = 992
- 163 + 829 = 992
- 181 + 811 = 992
- 223 + 769 = 992
- 241 + 751 = 992
- 283 + 709 = 992
Showing the first eight; more decompositions exist.
