Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87982, here are decompositions:
- 5 + 87977 = 87982
- 23 + 87959 = 87982
- 71 + 87911 = 87982
- 101 + 87881 = 87982
- 113 + 87869 = 87982
- 149 + 87833 = 87982
- 179 + 87803 = 87982
- 239 + 87743 = 87982
Showing the first eight; more decompositions exist.
