Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989884, here are decompositions:
- 11 + 989873 = 989884
- 47 + 989837 = 989884
- 53 + 989831 = 989884
- 101 + 989783 = 989884
- 107 + 989777 = 989884
- 131 + 989753 = 989884
- 197 + 989687 = 989884
- 443 + 989441 = 989884
Showing the first eight; more decompositions exist.
