Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15194, here are decompositions:

7 + 15187 = 15194
73 + 15121 = 15194
103 + 15091 = 15194
163 + 15031 = 15194
181 + 15013 = 15194
211 + 14983 = 15194
271 + 14923 = 15194
307 + 14887 = 15194

Showing the first eight; more decompositions exist.
