Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22820, here are decompositions:

3 + 22817 = 22820
13 + 22807 = 22820
37 + 22783 = 22820
43 + 22777 = 22820
79 + 22741 = 22820
103 + 22717 = 22820
151 + 22669 = 22820
181 + 22639 = 22820

Showing the first eight; more decompositions exist.
