Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15198, here are decompositions:
- 5 + 15193 = 15198
- 11 + 15187 = 15198
- 37 + 15161 = 15198
- 59 + 15139 = 15198
- 61 + 15137 = 15198
- 67 + 15131 = 15198
- 97 + 15101 = 15198
- 107 + 15091 = 15198
Showing the first eight; more decompositions exist.
