Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702182, here are decompositions:

3 + 8702179 = 8702182
23 + 8702159 = 8702182
89 + 8702093 = 8702182
131 + 8702051 = 8702182
173 + 8702009 = 8702182
191 + 8701991 = 8702182
233 + 8701949 = 8702182
311 + 8701871 = 8702182

Showing the first eight; more decompositions exist.
