Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19756, here are decompositions:

3 + 19753 = 19756
5 + 19751 = 19756
17 + 19739 = 19756
29 + 19727 = 19756
47 + 19709 = 19756
59 + 19697 = 19756
173 + 19583 = 19756
179 + 19577 = 19756

Showing the first eight; more decompositions exist.
