Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644270, here are decompositions:

17 + 8644253 = 8644270
83 + 8644187 = 8644270
113 + 8644157 = 8644270
179 + 8644091 = 8644270
251 + 8644019 = 8644270
311 + 8643959 = 8644270
317 + 8643953 = 8644270
347 + 8643923 = 8644270

Showing the first eight; more decompositions exist.
