Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7560, here are decompositions:

11 + 7549 = 7560
13 + 7547 = 7560
19 + 7541 = 7560
23 + 7537 = 7560
31 + 7529 = 7560
37 + 7523 = 7560
43 + 7517 = 7560
53 + 7507 = 7560

Showing the first eight; more decompositions exist.
