Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991060, here are decompositions:
- 3 + 991057 = 991060
- 17 + 991043 = 991060
- 23 + 991037 = 991060
- 29 + 991031 = 991060
- 71 + 990989 = 991060
- 107 + 990953 = 991060
- 137 + 990923 = 991060
- 167 + 990893 = 991060
Showing the first eight; more decompositions exist.
