Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22880, here are decompositions:

3 + 22877 = 22880
19 + 22861 = 22880
73 + 22807 = 22880
97 + 22783 = 22880
103 + 22777 = 22880
139 + 22741 = 22880
163 + 22717 = 22880
181 + 22699 = 22880

Showing the first eight; more decompositions exist.
