Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20120, here are decompositions:

3 + 20117 = 20120
7 + 20113 = 20120
13 + 20107 = 20120
19 + 20101 = 20120
31 + 20089 = 20120
73 + 20047 = 20120
97 + 20023 = 20120
109 + 20011 = 20120

Showing the first eight; more decompositions exist.
