Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22266, here are decompositions:

7 + 22259 = 22266
19 + 22247 = 22266
37 + 22229 = 22266
73 + 22193 = 22266
107 + 22159 = 22266
109 + 22157 = 22266
113 + 22153 = 22266
137 + 22129 = 22266

Showing the first eight; more decompositions exist.
