Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87916, here are decompositions:
- 5 + 87911 = 87916
- 29 + 87887 = 87916
- 47 + 87869 = 87916
- 83 + 87833 = 87916
- 113 + 87803 = 87916
- 149 + 87767 = 87916
- 173 + 87743 = 87916
- 197 + 87719 = 87916
Showing the first eight; more decompositions exist.
