Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651948, here are decompositions:

7 + 8651941 = 8651948
31 + 8651917 = 8651948
79 + 8651869 = 8651948
157 + 8651791 = 8651948
211 + 8651737 = 8651948
367 + 8651581 = 8651948
619 + 8651329 = 8651948
709 + 8651239 = 8651948

Showing the first eight; more decompositions exist.
