Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22808, here are decompositions:

31 + 22777 = 22808
67 + 22741 = 22808
109 + 22699 = 22808
139 + 22669 = 22808
157 + 22651 = 22808
241 + 22567 = 22808
277 + 22531 = 22808
307 + 22501 = 22808

Showing the first eight; more decompositions exist.
