Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188492, here are decompositions:

19 + 188473 = 188492
61 + 188431 = 188492
103 + 188389 = 188492
181 + 188311 = 188492
193 + 188299 = 188492
211 + 188281 = 188492
313 + 188179 = 188492
349 + 188143 = 188492

Showing the first eight; more decompositions exist.
