Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20090, here are decompositions:

19 + 20071 = 20090
43 + 20047 = 20090
61 + 20029 = 20090
67 + 20023 = 20090
79 + 20011 = 20090
97 + 19993 = 20090
127 + 19963 = 20090
163 + 19927 = 20090

Showing the first eight; more decompositions exist.
