Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174188, here are decompositions:

19 + 174169 = 174188
31 + 174157 = 174188
67 + 174121 = 174188
97 + 174091 = 174188
109 + 174079 = 174188
127 + 174061 = 174188
139 + 174049 = 174188
181 + 174007 = 174188

Showing the first eight; more decompositions exist.
