Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20948, here are decompositions:

19 + 20929 = 20948
61 + 20887 = 20948
139 + 20809 = 20948
199 + 20749 = 20948
229 + 20719 = 20948
241 + 20707 = 20948
307 + 20641 = 20948
337 + 20611 = 20948

Showing the first eight; more decompositions exist.
