Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15148, here are decompositions:

11 + 15137 = 15148
17 + 15131 = 15148
41 + 15107 = 15148
47 + 15101 = 15148
71 + 15077 = 15148
131 + 15017 = 15148
179 + 14969 = 15148
191 + 14957 = 15148

Showing the first eight; more decompositions exist.
