Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626392, here are decompositions:

43 + 8626349 = 8626392
109 + 8626283 = 8626392
149 + 8626243 = 8626392
163 + 8626229 = 8626392
211 + 8626181 = 8626392
223 + 8626169 = 8626392
233 + 8626159 = 8626392
251 + 8626141 = 8626392

Showing the first eight; more decompositions exist.
