Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20628, here are decompositions:

17 + 20611 = 20628
29 + 20599 = 20628
79 + 20549 = 20628
107 + 20521 = 20628
149 + 20479 = 20628
151 + 20477 = 20628
197 + 20431 = 20628
229 + 20399 = 20628

Showing the first eight; more decompositions exist.
