Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7530, here are decompositions:

7 + 7523 = 7530
13 + 7517 = 7530
23 + 7507 = 7530
31 + 7499 = 7530
41 + 7489 = 7530
43 + 7487 = 7530
53 + 7477 = 7530
71 + 7459 = 7530

Showing the first eight; more decompositions exist.
