Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659940, here are decompositions:

13 + 8659927 = 8659940
19 + 8659921 = 8659940
31 + 8659909 = 8659940
67 + 8659873 = 8659940
73 + 8659867 = 8659940
103 + 8659837 = 8659940
193 + 8659747 = 8659940
199 + 8659741 = 8659940

Showing the first eight; more decompositions exist.
