Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87994, here are decompositions:
- 3 + 87991 = 87994
- 17 + 87977 = 87994
- 83 + 87911 = 87994
- 107 + 87887 = 87994
- 113 + 87881 = 87994
- 191 + 87803 = 87994
- 197 + 87797 = 87994
- 227 + 87767 = 87994
Showing the first eight; more decompositions exist.
