Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999190, here are decompositions:
- 41 + 999149 = 999190
- 89 + 999101 = 999190
- 107 + 999083 = 999190
- 167 + 999023 = 999190
- 233 + 998957 = 999190
- 239 + 998951 = 999190
- 263 + 998927 = 999190
- 281 + 998909 = 999190
Showing the first eight; more decompositions exist.
