Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22858, here are decompositions:

5 + 22853 = 22858
41 + 22817 = 22858
47 + 22811 = 22858
71 + 22787 = 22858
89 + 22769 = 22858
107 + 22751 = 22858
131 + 22727 = 22858
137 + 22721 = 22858

Showing the first eight; more decompositions exist.
