Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15200, here are decompositions:

7 + 15193 = 15200
13 + 15187 = 15200
61 + 15139 = 15200
79 + 15121 = 15200
109 + 15091 = 15200
127 + 15073 = 15200
139 + 15061 = 15200
271 + 14929 = 15200

Showing the first eight; more decompositions exist.
