Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186174, here are decompositions:

11 + 186163 = 186174
13 + 186161 = 186174
17 + 186157 = 186174
61 + 186113 = 186174
67 + 186107 = 186174
71 + 186103 = 186174
103 + 186071 = 186174
137 + 186037 = 186174

Showing the first eight; more decompositions exist.
