Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15188, here are decompositions:

67 + 15121 = 15188
97 + 15091 = 15188
127 + 15061 = 15188
157 + 15031 = 15188
241 + 14947 = 15188
337 + 14851 = 15188
367 + 14821 = 15188
409 + 14779 = 15188

Showing the first eight; more decompositions exist.
