Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647948, here are decompositions:

11 + 8647937 = 8647948
59 + 8647889 = 8647948
131 + 8647817 = 8647948
251 + 8647697 = 8647948
359 + 8647589 = 8647948
479 + 8647469 = 8647948
557 + 8647391 = 8647948
599 + 8647349 = 8647948

Showing the first eight; more decompositions exist.
