Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644164, here are decompositions:

7 + 8644157 = 8644164
17 + 8644147 = 8644164
41 + 8644123 = 8644164
73 + 8644091 = 8644164
83 + 8644081 = 8644164
103 + 8644061 = 8644164
107 + 8644057 = 8644164
167 + 8643997 = 8644164

Showing the first eight; more decompositions exist.
