Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644122, here are decompositions:

31 + 8644091 = 8644122
41 + 8644081 = 8644122
61 + 8644061 = 8644122
73 + 8644049 = 8644122
103 + 8644019 = 8644122
131 + 8643991 = 8644122
163 + 8643959 = 8644122
181 + 8643941 = 8644122

Showing the first eight; more decompositions exist.
