Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22912, here are decompositions:

5 + 22907 = 22912
11 + 22901 = 22912
41 + 22871 = 22912
53 + 22859 = 22912
59 + 22853 = 22912
101 + 22811 = 22912
173 + 22739 = 22912
191 + 22721 = 22912

Showing the first eight; more decompositions exist.
