Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28026, here are decompositions:

7 + 28019 = 28026
29 + 27997 = 28026
43 + 27983 = 28026
59 + 27967 = 28026
73 + 27953 = 28026
79 + 27947 = 28026
83 + 27943 = 28026
107 + 27919 = 28026

Showing the first eight; more decompositions exist.
