Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627644, here are decompositions:

5 + 8627639 = 8627644
17 + 8627627 = 8627644
41 + 8627603 = 8627644
71 + 8627573 = 8627644
83 + 8627561 = 8627644
131 + 8627513 = 8627644
197 + 8627447 = 8627644
227 + 8627417 = 8627644

Showing the first eight; more decompositions exist.
