Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654720, here are decompositions:

7 + 8654713 = 8654720
31 + 8654689 = 8654720
79 + 8654641 = 8654720
103 + 8654617 = 8654720
157 + 8654563 = 8654720
199 + 8654521 = 8654720
331 + 8654389 = 8654720
421 + 8654299 = 8654720

Showing the first eight; more decompositions exist.
