Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188202, here are decompositions:

5 + 188197 = 188202
13 + 188189 = 188202
23 + 188179 = 188202
31 + 188171 = 188202
43 + 188159 = 188202
59 + 188143 = 188202
173 + 188029 = 188202
181 + 188021 = 188202

Showing the first eight; more decompositions exist.
