Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188304, here are decompositions:

5 + 188299 = 188304
13 + 188291 = 188304
23 + 188281 = 188304
31 + 188273 = 188304
43 + 188261 = 188304
107 + 188197 = 188304
157 + 188147 = 188304
167 + 188137 = 188304

Showing the first eight; more decompositions exist.
