Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611740, here are decompositions:

17 + 8611723 = 8611740
19 + 8611721 = 8611740
31 + 8611709 = 8611740
37 + 8611703 = 8611740
43 + 8611697 = 8611740
61 + 8611679 = 8611740
73 + 8611667 = 8611740
97 + 8611643 = 8611740

Showing the first eight; more decompositions exist.
