Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626422, here are decompositions:

5 + 8626417 = 8626422
31 + 8626391 = 8626422
73 + 8626349 = 8626422
139 + 8626283 = 8626422
151 + 8626271 = 8626422
173 + 8626249 = 8626422
179 + 8626243 = 8626422
193 + 8626229 = 8626422

Showing the first eight; more decompositions exist.
