Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644018, here are decompositions:

59 + 8643959 = 8644018
167 + 8643851 = 8644018
179 + 8643839 = 8644018
197 + 8643821 = 8644018
239 + 8643779 = 8644018
269 + 8643749 = 8644018
311 + 8643707 = 8644018
347 + 8643671 = 8644018

Showing the first eight; more decompositions exist.
