Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187202, here are decompositions:

13 + 187189 = 187202
31 + 187171 = 187202
61 + 187141 = 187202
73 + 187129 = 187202
79 + 187123 = 187202
193 + 187009 = 187202
199 + 187003 = 187202
313 + 186889 = 187202

Showing the first eight; more decompositions exist.
