Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188862, here are decompositions:

5 + 188857 = 188862
19 + 188843 = 188862
29 + 188833 = 188862
31 + 188831 = 188862
61 + 188801 = 188862
71 + 188791 = 188862
83 + 188779 = 188862
109 + 188753 = 188862

Showing the first eight; more decompositions exist.
