Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650940, here are decompositions:

13 + 8650927 = 8650940
43 + 8650897 = 8650940
61 + 8650879 = 8650940
127 + 8650813 = 8650940
163 + 8650777 = 8650940
271 + 8650669 = 8650940
283 + 8650657 = 8650940
307 + 8650633 = 8650940

Showing the first eight; more decompositions exist.
