Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5640, here are decompositions:

17 + 5623 = 5640
59 + 5581 = 5640
67 + 5573 = 5640
71 + 5569 = 5640
83 + 5557 = 5640
109 + 5531 = 5640
113 + 5527 = 5640
137 + 5503 = 5640

Showing the first eight; more decompositions exist.
