Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20096, here are decompositions:

7 + 20089 = 20096
67 + 20029 = 20096
73 + 20023 = 20096
103 + 19993 = 20096
229 + 19867 = 20096
277 + 19819 = 20096
283 + 19813 = 20096
337 + 19759 = 20096

Showing the first eight; more decompositions exist.
