Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646426, here are decompositions:

23 + 8646403 = 8646426
37 + 8646389 = 8646426
97 + 8646329 = 8646426
109 + 8646317 = 8646426
127 + 8646299 = 8646426
149 + 8646277 = 8646426
157 + 8646269 = 8646426
167 + 8646259 = 8646426

Showing the first eight; more decompositions exist.
