Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22756, here are decompositions:

5 + 22751 = 22756
17 + 22739 = 22756
29 + 22727 = 22756
47 + 22709 = 22756
59 + 22697 = 22756
113 + 22643 = 22756
137 + 22619 = 22756
347 + 22409 = 22756

Showing the first eight; more decompositions exist.
