Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15108, here are decompositions:
- 7 + 15101 = 15108
- 17 + 15091 = 15108
- 31 + 15077 = 15108
- 47 + 15061 = 15108
- 139 + 14969 = 15108
- 151 + 14957 = 15108
- 157 + 14951 = 15108
- 179 + 14929 = 15108
Showing the first eight; more decompositions exist.
