Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745644, here are decompositions:

7 + 8745637 = 8745644
31 + 8745613 = 8745644
73 + 8745571 = 8745644
97 + 8745547 = 8745644
151 + 8745493 = 8745644
277 + 8745367 = 8745644
337 + 8745307 = 8745644
421 + 8745223 = 8745644

Showing the first eight; more decompositions exist.
