Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186192, here are decompositions:

5 + 186187 = 186192
29 + 186163 = 186192
31 + 186161 = 186192
43 + 186149 = 186192
73 + 186119 = 186192
79 + 186113 = 186192
89 + 186103 = 186192
151 + 186041 = 186192

Showing the first eight; more decompositions exist.
