Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650740, here are decompositions:

13 + 8650727 = 8650740
17 + 8650723 = 8650740
19 + 8650721 = 8650740
31 + 8650709 = 8650740
37 + 8650703 = 8650740
53 + 8650687 = 8650740
67 + 8650673 = 8650740
71 + 8650669 = 8650740

Showing the first eight; more decompositions exist.
