Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647976, here are decompositions:

13 + 8647963 = 8647976
79 + 8647897 = 8647976
97 + 8647879 = 8647976
157 + 8647819 = 8647976
193 + 8647783 = 8647976
223 + 8647753 = 8647976
277 + 8647699 = 8647976
397 + 8647579 = 8647976

Showing the first eight; more decompositions exist.
