Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188542, here are decompositions:

23 + 188519 = 188542
59 + 188483 = 188542
83 + 188459 = 188542
173 + 188369 = 188542
191 + 188351 = 188542
239 + 188303 = 188542
251 + 188291 = 188542
269 + 188273 = 188542

Showing the first eight; more decompositions exist.
