Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654840, here are decompositions:

3 + 8654837 = 8654840
31 + 8654809 = 8654840
37 + 8654803 = 8654840
67 + 8654773 = 8654840
79 + 8654761 = 8654840
127 + 8654713 = 8654840
151 + 8654689 = 8654840
199 + 8654641 = 8654840

Showing the first eight; more decompositions exist.
