Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22800, here are decompositions:

13 + 22787 = 22800
17 + 22783 = 22800
23 + 22777 = 22800
31 + 22769 = 22800
59 + 22741 = 22800
61 + 22739 = 22800
73 + 22727 = 22800
79 + 22721 = 22800

Showing the first eight; more decompositions exist.
