Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987892, here are decompositions:
- 23 + 987869 = 987892
- 41 + 987851 = 987892
- 71 + 987821 = 987892
- 83 + 987809 = 987892
- 89 + 987803 = 987892
- 179 + 987713 = 987892
- 233 + 987659 = 987892
- 293 + 987599 = 987892
Showing the first eight; more decompositions exist.
