Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20676, here are decompositions:

13 + 20663 = 20676
37 + 20639 = 20676
83 + 20593 = 20676
113 + 20563 = 20676
127 + 20549 = 20676
167 + 20509 = 20676
193 + 20483 = 20676
197 + 20479 = 20676

Showing the first eight; more decompositions exist.
