Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188292, here are decompositions:

11 + 188281 = 188292
19 + 188273 = 188292
31 + 188261 = 188292
43 + 188249 = 188292
103 + 188189 = 188292
113 + 188179 = 188292
149 + 188143 = 188292
263 + 188029 = 188292

Showing the first eight; more decompositions exist.
