Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15186, here are decompositions:

13 + 15173 = 15186
37 + 15149 = 15186
47 + 15139 = 15186
79 + 15107 = 15186
103 + 15083 = 15186
109 + 15077 = 15186
113 + 15073 = 15186
173 + 15013 = 15186

Showing the first eight; more decompositions exist.
