Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16170, here are decompositions:

29 + 16141 = 16170
31 + 16139 = 16170
43 + 16127 = 16170
59 + 16111 = 16170
67 + 16103 = 16170
73 + 16097 = 16170
79 + 16091 = 16170
83 + 16087 = 16170

Showing the first eight; more decompositions exist.
