Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103212, here are decompositions:

29 + 103183 = 103212
41 + 103171 = 103212
71 + 103141 = 103212
89 + 103123 = 103212
113 + 103099 = 103212
163 + 103049 = 103212
211 + 103001 = 103212
229 + 102983 = 103212

Showing the first eight; more decompositions exist.
