Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644086, here are decompositions:

5 + 8644081 = 8644086
29 + 8644057 = 8644086
37 + 8644049 = 8644086
67 + 8644019 = 8644086
89 + 8643997 = 8644086
127 + 8643959 = 8644086
163 + 8643923 = 8644086
167 + 8643919 = 8644086

Showing the first eight; more decompositions exist.
