Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188816, here are decompositions:

37 + 188779 = 188816
97 + 188719 = 188816
109 + 188707 = 188816
139 + 188677 = 188816
163 + 188653 = 188816
283 + 188533 = 188816
373 + 188443 = 188816
379 + 188437 = 188816

Showing the first eight; more decompositions exist.
