Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626444, here are decompositions:

23 + 8626421 = 8626444
53 + 8626391 = 8626444
173 + 8626271 = 8626444
263 + 8626181 = 8626444
383 + 8626061 = 8626444
401 + 8626043 = 8626444
443 + 8626001 = 8626444
461 + 8625983 = 8626444

Showing the first eight; more decompositions exist.
