Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188182, here are decompositions:

3 + 188179 = 188182
11 + 188171 = 188182
23 + 188159 = 188182
251 + 187931 = 188182
311 + 187871 = 188182
359 + 187823 = 188182
389 + 187793 = 188182
419 + 187763 = 188182

Showing the first eight; more decompositions exist.
