Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7524, here are decompositions:

7 + 7517 = 7524
17 + 7507 = 7524
37 + 7487 = 7524
43 + 7481 = 7524
47 + 7477 = 7524
67 + 7457 = 7524
73 + 7451 = 7524
107 + 7417 = 7524

Showing the first eight; more decompositions exist.
