Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644072, here are decompositions:

11 + 8644061 = 8644072
23 + 8644049 = 8644072
53 + 8644019 = 8644072
113 + 8643959 = 8644072
131 + 8643941 = 8644072
149 + 8643923 = 8644072
179 + 8643893 = 8644072
233 + 8643839 = 8644072

Showing the first eight; more decompositions exist.
