Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987108, here are decompositions:
- 7 + 987101 = 987108
- 11 + 987097 = 987108
- 19 + 987089 = 987108
- 29 + 987079 = 987108
- 41 + 987067 = 987108
- 47 + 987061 = 987108
- 79 + 987029 = 987108
- 127 + 986981 = 987108
Showing the first eight; more decompositions exist.
