Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15210, here are decompositions:

11 + 15199 = 15210
17 + 15193 = 15210
23 + 15187 = 15210
37 + 15173 = 15210
61 + 15149 = 15210
71 + 15139 = 15210
73 + 15137 = 15210
79 + 15131 = 15210

Showing the first eight; more decompositions exist.
