Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680740, here are decompositions:

7 + 8680733 = 8680740
17 + 8680723 = 8680740
23 + 8680717 = 8680740
41 + 8680699 = 8680740
43 + 8680697 = 8680740
71 + 8680669 = 8680740
109 + 8680631 = 8680740
127 + 8680613 = 8680740

Showing the first eight; more decompositions exist.
