Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188874, here are decompositions:

5 + 188869 = 188874
11 + 188863 = 188874
13 + 188861 = 188874
17 + 188857 = 188874
31 + 188843 = 188874
41 + 188833 = 188874
43 + 188831 = 188874
47 + 188827 = 188874

Showing the first eight; more decompositions exist.
