Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89188, here are decompositions:
- 101 + 89087 = 89188
- 131 + 89057 = 89188
- 137 + 89051 = 89188
- 167 + 89021 = 89188
- 179 + 89009 = 89188
- 191 + 88997 = 89188
- 251 + 88937 = 89188
- 269 + 88919 = 89188
Showing the first eight; more decompositions exist.
