Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624894, here are decompositions:

7 + 8624887 = 8624894
13 + 8624881 = 8624894
73 + 8624821 = 8624894
181 + 8624713 = 8624894
277 + 8624617 = 8624894
541 + 8624353 = 8624894
571 + 8624323 = 8624894
643 + 8624251 = 8624894

Showing the first eight; more decompositions exist.
