Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22186, here are decompositions:

29 + 22157 = 22186
53 + 22133 = 22186
107 + 22079 = 22186
113 + 22073 = 22186
149 + 22037 = 22186
173 + 22013 = 22186
257 + 21929 = 22186
293 + 21893 = 22186

Showing the first eight; more decompositions exist.
