Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644158, here are decompositions:

11 + 8644147 = 8644158
67 + 8644091 = 8644158
97 + 8644061 = 8644158
101 + 8644057 = 8644158
109 + 8644049 = 8644158
139 + 8644019 = 8644158
167 + 8643991 = 8644158
199 + 8643959 = 8644158

Showing the first eight; more decompositions exist.
