Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489808, here are decompositions:
- 5 + 489803 = 489808
- 17 + 489791 = 489808
- 47 + 489761 = 489808
- 131 + 489677 = 489808
- 149 + 489659 = 489808
- 251 + 489557 = 489808
- 257 + 489551 = 489808
- 269 + 489539 = 489808
Showing the first eight; more decompositions exist.
