Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20108, here are decompositions:

7 + 20101 = 20108
19 + 20089 = 20108
37 + 20071 = 20108
61 + 20047 = 20108
79 + 20029 = 20108
97 + 20011 = 20108
181 + 19927 = 20108
241 + 19867 = 20108

Showing the first eight; more decompositions exist.
