Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188260, here are decompositions:

11 + 188249 = 188260
71 + 188189 = 188260
89 + 188171 = 188260
101 + 188159 = 188260
113 + 188147 = 188260
239 + 188021 = 188260
353 + 187907 = 188260
383 + 187877 = 188260

Showing the first eight; more decompositions exist.
