Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188284, here are decompositions:

3 + 188281 = 188284
11 + 188273 = 188284
23 + 188261 = 188284
113 + 188171 = 188284
137 + 188147 = 188284
263 + 188021 = 188284
311 + 187973 = 188284
353 + 187931 = 188284

Showing the first eight; more decompositions exist.
