Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9992, here are decompositions:
- 19 + 9973 = 9992
- 43 + 9949 = 9992
- 61 + 9931 = 9992
- 109 + 9883 = 9992
- 163 + 9829 = 9992
- 181 + 9811 = 9992
- 211 + 9781 = 9992
- 223 + 9769 = 9992
Showing the first eight; more decompositions exist.
