Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20952, here are decompositions:

5 + 20947 = 20952
13 + 20939 = 20952
23 + 20929 = 20952
31 + 20921 = 20952
53 + 20899 = 20952
73 + 20879 = 20952
79 + 20873 = 20952
103 + 20849 = 20952

Showing the first eight; more decompositions exist.
