Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188850, here are decompositions:

7 + 188843 = 188850
17 + 188833 = 188850
19 + 188831 = 188850
23 + 188827 = 188850
59 + 188791 = 188850
71 + 188779 = 188850
83 + 188767 = 188850
97 + 188753 = 188850

Showing the first eight; more decompositions exist.
