Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26820, here are decompositions:

7 + 26813 = 26820
19 + 26801 = 26820
37 + 26783 = 26820
43 + 26777 = 26820
61 + 26759 = 26820
83 + 26737 = 26820
89 + 26731 = 26820
97 + 26723 = 26820

Showing the first eight; more decompositions exist.
