Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189168, here are decompositions:

17 + 189151 = 189168
19 + 189149 = 189168
29 + 189139 = 189168
41 + 189127 = 189168
101 + 189067 = 189168
107 + 189061 = 189168
127 + 189041 = 189168
149 + 189019 = 189168

Showing the first eight; more decompositions exist.
