Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644012, here are decompositions:

53 + 8643959 = 8644012
59 + 8643953 = 8644012
71 + 8643941 = 8644012
89 + 8643923 = 8644012
173 + 8643839 = 8644012
191 + 8643821 = 8644012
233 + 8643779 = 8644012
263 + 8643749 = 8644012

Showing the first eight; more decompositions exist.
