Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609740, here are decompositions:

11 + 8609729 = 8609740
53 + 8609687 = 8609740
71 + 8609669 = 8609740
89 + 8609651 = 8609740
101 + 8609639 = 8609740
131 + 8609609 = 8609740
149 + 8609591 = 8609740
239 + 8609501 = 8609740

Showing the first eight; more decompositions exist.
