Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20048, here are decompositions:

19 + 20029 = 20048
37 + 20011 = 20048
157 + 19891 = 20048
181 + 19867 = 20048
229 + 19819 = 20048
271 + 19777 = 20048
331 + 19717 = 20048
349 + 19699 = 20048

Showing the first eight; more decompositions exist.
