Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9212, here are decompositions:

3 + 9209 = 9212
13 + 9199 = 9212
31 + 9181 = 9212
61 + 9151 = 9212
79 + 9133 = 9212
103 + 9109 = 9212
109 + 9103 = 9212
163 + 9049 = 9212

Showing the first eight; more decompositions exist.
