Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626432, here are decompositions:

11 + 8626421 = 8626432
41 + 8626391 = 8626432
83 + 8626349 = 8626432
131 + 8626301 = 8626432
149 + 8626283 = 8626432
251 + 8626181 = 8626432
263 + 8626169 = 8626432
293 + 8626139 = 8626432

Showing the first eight; more decompositions exist.
