Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989118, here are decompositions:
- 19 + 989099 = 989118
- 37 + 989081 = 989118
- 47 + 989071 = 989118
- 59 + 989059 = 989118
- 89 + 989029 = 989118
- 107 + 989011 = 989118
- 139 + 988979 = 989118
- 167 + 988951 = 989118
Showing the first eight; more decompositions exist.
