Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646432, here are decompositions:

29 + 8646403 = 8646432
31 + 8646401 = 8646432
43 + 8646389 = 8646432
71 + 8646361 = 8646432
103 + 8646329 = 8646432
139 + 8646293 = 8646432
163 + 8646269 = 8646432
173 + 8646259 = 8646432

Showing the first eight; more decompositions exist.
