Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187108, here are decompositions:
- 17 + 187091 = 187108
- 41 + 187067 = 187108
- 59 + 187049 = 187108
- 149 + 186959 = 187108
- 191 + 186917 = 187108
- 239 + 186869 = 187108
- 347 + 186761 = 187108
- 401 + 186707 = 187108
Showing the first eight; more decompositions exist.
