Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185202, here are decompositions:

13 + 185189 = 185202
19 + 185183 = 185202
41 + 185161 = 185202
53 + 185149 = 185202
71 + 185131 = 185202
79 + 185123 = 185202
103 + 185099 = 185202
113 + 185089 = 185202

Showing the first eight; more decompositions exist.
