Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28020, here are decompositions:

19 + 28001 = 28020
23 + 27997 = 28020
37 + 27983 = 28020
53 + 27967 = 28020
59 + 27961 = 28020
67 + 27953 = 28020
73 + 27947 = 28020
79 + 27941 = 28020

Showing the first eight; more decompositions exist.
