Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186202, here are decompositions:

11 + 186191 = 186202
41 + 186161 = 186202
53 + 186149 = 186202
83 + 186119 = 186202
89 + 186113 = 186202
131 + 186071 = 186202
179 + 186023 = 186202
251 + 185951 = 186202

Showing the first eight; more decompositions exist.
