Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22900, here are decompositions:

23 + 22877 = 22900
29 + 22871 = 22900
41 + 22859 = 22900
47 + 22853 = 22900
83 + 22817 = 22900
89 + 22811 = 22900
113 + 22787 = 22900
131 + 22769 = 22900

Showing the first eight; more decompositions exist.
