Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22918, here are decompositions:

11 + 22907 = 22918
17 + 22901 = 22918
41 + 22877 = 22918
47 + 22871 = 22918
59 + 22859 = 22918
101 + 22817 = 22918
107 + 22811 = 22918
131 + 22787 = 22918

Showing the first eight; more decompositions exist.
