Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20756, here are decompositions:

3 + 20753 = 20756
7 + 20749 = 20756
13 + 20743 = 20756
37 + 20719 = 20756
157 + 20599 = 20756
163 + 20593 = 20756
193 + 20563 = 20756
223 + 20533 = 20756

Showing the first eight; more decompositions exist.
