Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189982, here are decompositions:

5 + 189977 = 189982
53 + 189929 = 189982
101 + 189881 = 189982
131 + 189851 = 189982
239 + 189743 = 189982
269 + 189713 = 189982
281 + 189701 = 189982
311 + 189671 = 189982

Showing the first eight; more decompositions exist.
