Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188838, here are decompositions:

5 + 188833 = 188838
7 + 188831 = 188838
11 + 188827 = 188838
37 + 188801 = 188838
47 + 188791 = 188838
59 + 188779 = 188838
71 + 188767 = 188838
109 + 188729 = 188838

Showing the first eight; more decompositions exist.
