Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489906, here are decompositions:
- 5 + 489901 = 489906
- 19 + 489887 = 489906
- 37 + 489869 = 489906
- 59 + 489847 = 489906
- 73 + 489833 = 489906
- 83 + 489823 = 489906
- 89 + 489817 = 489906
- 103 + 489803 = 489906
Showing the first eight; more decompositions exist.
