Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683940, here are decompositions:

7 + 8683933 = 8683940
43 + 8683897 = 8683940
157 + 8683783 = 8683940
211 + 8683729 = 8683940
241 + 8683699 = 8683940
277 + 8683663 = 8683940
283 + 8683657 = 8683940
337 + 8683603 = 8683940

Showing the first eight; more decompositions exist.
