Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20760, here are decompositions:

7 + 20753 = 20760
11 + 20749 = 20760
13 + 20747 = 20760
17 + 20743 = 20760
29 + 20731 = 20760
41 + 20719 = 20760
43 + 20717 = 20760
53 + 20707 = 20760

Showing the first eight; more decompositions exist.
