Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15252, here are decompositions:

11 + 15241 = 15252
19 + 15233 = 15252
53 + 15199 = 15252
59 + 15193 = 15252
79 + 15173 = 15252
103 + 15149 = 15252
113 + 15139 = 15252
131 + 15121 = 15252

Showing the first eight; more decompositions exist.
