Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22210, here are decompositions:

17 + 22193 = 22210
53 + 22157 = 22210
101 + 22109 = 22210
131 + 22079 = 22210
137 + 22073 = 22210
173 + 22037 = 22210
179 + 22031 = 22210
197 + 22013 = 22210

Showing the first eight; more decompositions exist.
