Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489048, here are decompositions:
- 5 + 489043 = 489048
- 29 + 489019 = 489048
- 37 + 489011 = 489048
- 47 + 489001 = 489048
- 67 + 488981 = 489048
- 89 + 488959 = 489048
- 101 + 488947 = 489048
- 127 + 488921 = 489048
Showing the first eight; more decompositions exist.
