Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169188, here are decompositions:

7 + 169181 = 169188
11 + 169177 = 169188
29 + 169159 = 169188
37 + 169151 = 169188
59 + 169129 = 169188
109 + 169079 = 169188
139 + 169049 = 169188
179 + 169009 = 169188

Showing the first eight; more decompositions exist.
