Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644408, here are decompositions:

11 + 8644397 = 8644408
107 + 8644301 = 8644408
251 + 8644157 = 8644408
317 + 8644091 = 8644408
347 + 8644061 = 8644408
359 + 8644049 = 8644408
389 + 8644019 = 8644408
449 + 8643959 = 8644408

Showing the first eight; more decompositions exist.
