Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989016, here are decompositions:
- 5 + 989011 = 989016
- 37 + 988979 = 989016
- 53 + 988963 = 989016
- 79 + 988937 = 989016
- 107 + 988909 = 989016
- 139 + 988877 = 989016
- 157 + 988859 = 989016
- 167 + 988849 = 989016
Showing the first eight; more decompositions exist.
