Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15208, here are decompositions:
- 47 + 15161 = 15208
- 59 + 15149 = 15208
- 71 + 15137 = 15208
- 101 + 15107 = 15208
- 107 + 15101 = 15208
- 131 + 15077 = 15208
- 191 + 15017 = 15208
- 239 + 14969 = 15208
Showing the first eight; more decompositions exist.
