Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187194, here are decompositions:

5 + 187189 = 187194
13 + 187181 = 187194
17 + 187177 = 187194
23 + 187171 = 187194
31 + 187163 = 187194
53 + 187141 = 187194
61 + 187133 = 187194
67 + 187127 = 187194

Showing the first eight; more decompositions exist.
