Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653940, here are decompositions:

3 + 8653937 = 8653940
37 + 8653903 = 8653940
151 + 8653789 = 8653940
199 + 8653741 = 8653940
223 + 8653717 = 8653940
241 + 8653699 = 8653940
271 + 8653669 = 8653940
283 + 8653657 = 8653940

Showing the first eight; more decompositions exist.
