Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646644, here are decompositions:

37 + 8646607 = 8646644
73 + 8646571 = 8646644
157 + 8646487 = 8646644
241 + 8646403 = 8646644
283 + 8646361 = 8646644
367 + 8646277 = 8646644
397 + 8646247 = 8646644
421 + 8646223 = 8646644

Showing the first eight; more decompositions exist.
