Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29992, here are decompositions:
- 3 + 29989 = 29992
- 71 + 29921 = 29992
- 113 + 29879 = 29992
- 173 + 29819 = 29992
- 233 + 29759 = 29992
- 239 + 29753 = 29992
- 251 + 29741 = 29992
- 269 + 29723 = 29992
Showing the first eight; more decompositions exist.
