Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53640, here are decompositions:

7 + 53633 = 53640
11 + 53629 = 53640
17 + 53623 = 53640
23 + 53617 = 53640
29 + 53611 = 53640
31 + 53609 = 53640
43 + 53597 = 53640
47 + 53593 = 53640

Showing the first eight; more decompositions exist.
