Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15174, here are decompositions:

13 + 15161 = 15174
37 + 15137 = 15174
43 + 15131 = 15174
53 + 15121 = 15174
67 + 15107 = 15174
73 + 15101 = 15174
83 + 15091 = 15174
97 + 15077 = 15174

Showing the first eight; more decompositions exist.
