Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190188, here are decompositions:

7 + 190181 = 190188
29 + 190159 = 190188
41 + 190147 = 190188
59 + 190129 = 190188
67 + 190121 = 190188
137 + 190051 = 190188
157 + 190031 = 190188
191 + 189997 = 190188

Showing the first eight; more decompositions exist.
