Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489560, here are decompositions:
- 3 + 489557 = 489560
- 7 + 489553 = 489560
- 31 + 489529 = 489560
- 67 + 489493 = 489560
- 73 + 489487 = 489560
- 103 + 489457 = 489560
- 151 + 489409 = 489560
- 193 + 489367 = 489560
Showing the first eight; more decompositions exist.
