Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489576, here are decompositions:
- 5 + 489571 = 489576
- 19 + 489557 = 489576
- 23 + 489553 = 489576
- 37 + 489539 = 489576
- 47 + 489529 = 489576
- 83 + 489493 = 489576
- 89 + 489487 = 489576
- 97 + 489479 = 489576
Showing the first eight; more decompositions exist.
