Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188272, here are decompositions:

11 + 188261 = 188272
23 + 188249 = 188272
83 + 188189 = 188272
101 + 188171 = 188272
113 + 188159 = 188272
251 + 188021 = 188272
389 + 187883 = 188272
401 + 187871 = 188272

Showing the first eight; more decompositions exist.
