Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987306, here are decompositions:
- 7 + 987299 = 987306
- 13 + 987293 = 987306
- 79 + 987227 = 987306
- 97 + 987209 = 987306
- 107 + 987199 = 987306
- 113 + 987193 = 987306
- 163 + 987143 = 987306
- 179 + 987127 = 987306
Showing the first eight; more decompositions exist.
