Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990448, here are decompositions:
- 59 + 990389 = 990448
- 71 + 990377 = 990448
- 89 + 990359 = 990448
- 167 + 990281 = 990448
- 269 + 990179 = 990448
- 311 + 990137 = 990448
- 449 + 989999 = 990448
- 467 + 989981 = 990448
Showing the first eight; more decompositions exist.
