Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489108, here are decompositions:
- 7 + 489101 = 489108
- 47 + 489061 = 489108
- 89 + 489019 = 489108
- 97 + 489011 = 489108
- 107 + 489001 = 489108
- 127 + 488981 = 489108
- 149 + 488959 = 489108
- 199 + 488909 = 489108
Showing the first eight; more decompositions exist.
