Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647040, here are decompositions:

13 + 8647027 = 8647040
19 + 8647021 = 8647040
79 + 8646961 = 8647040
97 + 8646943 = 8647040
151 + 8646889 = 8647040
223 + 8646817 = 8647040
331 + 8646709 = 8647040
373 + 8646667 = 8647040

Showing the first eight; more decompositions exist.
