Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20084, here are decompositions:

13 + 20071 = 20084
37 + 20047 = 20084
61 + 20023 = 20084
73 + 20011 = 20084
157 + 19927 = 20084
193 + 19891 = 20084
223 + 19861 = 20084
241 + 19843 = 20084

Showing the first eight; more decompositions exist.
