Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87898, here are decompositions:
- 11 + 87887 = 87898
- 17 + 87881 = 87898
- 29 + 87869 = 87898
- 101 + 87797 = 87898
- 131 + 87767 = 87898
- 179 + 87719 = 87898
- 197 + 87701 = 87898
- 227 + 87671 = 87898
Showing the first eight; more decompositions exist.
