Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186404, here are decompositions:

7 + 186397 = 186404
13 + 186391 = 186404
61 + 186343 = 186404
103 + 186301 = 186404
151 + 186253 = 186404
157 + 186247 = 186404
193 + 186211 = 186404
241 + 186163 = 186404

Showing the first eight; more decompositions exist.
