Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22872, here are decompositions:

11 + 22861 = 22872
13 + 22859 = 22872
19 + 22853 = 22872
61 + 22811 = 22872
89 + 22783 = 22872
103 + 22769 = 22872
131 + 22741 = 22872
151 + 22721 = 22872

Showing the first eight; more decompositions exist.
