Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644210, here are decompositions:

23 + 8644187 = 8644210
53 + 8644157 = 8644210
149 + 8644061 = 8644210
191 + 8644019 = 8644210
251 + 8643959 = 8644210
257 + 8643953 = 8644210
269 + 8643941 = 8644210
317 + 8643893 = 8644210

Showing the first eight; more decompositions exist.
