Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188584, here are decompositions:

5 + 188579 = 188584
101 + 188483 = 188584
167 + 188417 = 188584
233 + 188351 = 188584
251 + 188333 = 188584
281 + 188303 = 188584
293 + 188291 = 188584
311 + 188273 = 188584

Showing the first eight; more decompositions exist.
