Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20766, here are decompositions:

7 + 20759 = 20766
13 + 20753 = 20766
17 + 20749 = 20766
19 + 20747 = 20766
23 + 20743 = 20766
47 + 20719 = 20766
59 + 20707 = 20766
73 + 20693 = 20766

Showing the first eight; more decompositions exist.
