Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644360, here are decompositions:

29 + 8644331 = 8644360
59 + 8644301 = 8644360
107 + 8644253 = 8644360
173 + 8644187 = 8644360
269 + 8644091 = 8644360
311 + 8644049 = 8644360
401 + 8643959 = 8644360
419 + 8643941 = 8644360

Showing the first eight; more decompositions exist.
