Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655740, here are decompositions:

7 + 8655733 = 8655740
19 + 8655721 = 8655740
61 + 8655679 = 8655740
103 + 8655637 = 8655740
109 + 8655631 = 8655740
283 + 8655457 = 8655740
307 + 8655433 = 8655740
337 + 8655403 = 8655740

Showing the first eight; more decompositions exist.
