Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681740, here are decompositions:

3 + 8681737 = 8681740
47 + 8681693 = 8681740
71 + 8681669 = 8681740
101 + 8681639 = 8681740
173 + 8681567 = 8681740
191 + 8681549 = 8681740
227 + 8681513 = 8681740
233 + 8681507 = 8681740

Showing the first eight; more decompositions exist.
