Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740, here are decompositions:

3 + 8737 = 8740
41 + 8699 = 8740
47 + 8693 = 8740
59 + 8681 = 8740
71 + 8669 = 8740
113 + 8627 = 8740
131 + 8609 = 8740
167 + 8573 = 8740

Showing the first eight; more decompositions exist.
