Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15170, here are decompositions:

31 + 15139 = 15170
79 + 15091 = 15170
97 + 15073 = 15170
109 + 15061 = 15170
139 + 15031 = 15170
157 + 15013 = 15170
223 + 14947 = 15170
241 + 14929 = 15170

Showing the first eight; more decompositions exist.
