Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008880, here are decompositions:
- 17 + 1008863 = 1008880
- 23 + 1008857 = 1008880
- 29 + 1008851 = 1008880
- 71 + 1008809 = 1008880
- 101 + 1008779 = 1008880
- 107 + 1008773 = 1008880
- 137 + 1008743 = 1008880
- 179 + 1008701 = 1008880
Showing the first eight; more decompositions exist.
