Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998992, here are decompositions:
- 3 + 998989 = 998992
- 23 + 998969 = 998992
- 41 + 998951 = 998992
- 83 + 998909 = 998992
- 131 + 998861 = 998992
- 149 + 998843 = 998992
- 173 + 998819 = 998992
- 179 + 998813 = 998992
Showing the first eight; more decompositions exist.
