Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188392, here are decompositions:

3 + 188389 = 188392
23 + 188369 = 188392
41 + 188351 = 188392
59 + 188333 = 188392
89 + 188303 = 188392
101 + 188291 = 188392
131 + 188261 = 188392
233 + 188159 = 188392

Showing the first eight; more decompositions exist.
