Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644068, here are decompositions:

7 + 8644061 = 8644068
11 + 8644057 = 8644068
19 + 8644049 = 8644068
71 + 8643997 = 8644068
109 + 8643959 = 8644068
127 + 8643941 = 8644068
149 + 8643919 = 8644068
179 + 8643889 = 8644068

Showing the first eight; more decompositions exist.
