Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15136, here are decompositions:

5 + 15131 = 15136
29 + 15107 = 15136
53 + 15083 = 15136
59 + 15077 = 15136
83 + 15053 = 15136
167 + 14969 = 15136
179 + 14957 = 15136
197 + 14939 = 15136

Showing the first eight; more decompositions exist.
