Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22006, here are decompositions:

3 + 22003 = 22006
29 + 21977 = 22006
113 + 21893 = 22006
167 + 21839 = 22006
233 + 21773 = 22006
239 + 21767 = 22006
269 + 21737 = 22006
293 + 21713 = 22006

Showing the first eight; more decompositions exist.
