Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742644, here are decompositions:

7 + 8742637 = 8742644
67 + 8742577 = 8742644
73 + 8742571 = 8742644
103 + 8742541 = 8742644
151 + 8742493 = 8742644
181 + 8742463 = 8742644
223 + 8742421 = 8742644
277 + 8742367 = 8742644

Showing the first eight; more decompositions exist.
