Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999238, here are decompositions:
- 5 + 999233 = 999238
- 17 + 999221 = 999238
- 89 + 999149 = 999238
- 137 + 999101 = 999238
- 269 + 998969 = 999238
- 281 + 998957 = 999238
- 311 + 998927 = 999238
- 419 + 998819 = 999238
Showing the first eight; more decompositions exist.
