Goldbach decomposition

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.
