Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15168, here are decompositions:
- 7 + 15161 = 15168
- 19 + 15149 = 15168
- 29 + 15139 = 15168
- 31 + 15137 = 15168
- 37 + 15131 = 15168
- 47 + 15121 = 15168
- 61 + 15107 = 15168
- 67 + 15101 = 15168
Showing the first eight; more decompositions exist.
